SaaS development cost in 2026: build, fees, hosting and what Deepsel charges

Published October 7, 2026

SaaS development cost runs $30,000 to $150,000 for a first version at the agencies that publish prices, and $100,000 to $500,000 or more for a full platform. Those are vendors' figures: Brocoders lists $30,000 to $150,000 for a focused MVP and Classic Informatics $40,000 to $90,000 over three to five months, both fetched October 2026. Founders on Reddit report paying $2,500 to $20,000 for a first version from a freelancer or a small studio, and one small shop published its last twelve builds at $6,500 to $61,000 with a median near $21,000. On Deepsel's SaaS development retainer, a typical startup MVP ships inside 1 to 2 months at $15,000 a month, so $15,000 to $30,000, with the SaaS pieces (tenancy, billing, roles) pushing toward the top of that window. Then come the bills most cost guides leave out. Stripe takes 2.9% plus 30 cents of every card payment and Stripe Billing another 0.7%, and the hosting stack for an early product lists at about $25 to $75 a month. Every number below has its source and date next to it.

Why two SaaS quotes for the same product differ tenfold

Three things, and none of them is dishonesty. First, "SaaS MVP" means different things to different builders: one user and one flow, or a product a company can pay for and run its team on. Second, the hourly rate behind the quote runs from $25 to $275 depending on where the team sits (the regional table is further down). Third, what gets counted. A quote that includes subscription billing, tenant isolation and an admin back office is a different product from one that stops at a dashboard with a login, and both get called a SaaS.

Here's the published spread, so you can see where the quote in your inbox sits. All of these are vendors' asking prices or estimates, so read them as the market's price list rather than as what buyers paid.

The bottom and top rows describe overlapping products at a twentyfold gap: EnactOn's $5,000 to $20,000 and ScienceSoft's $100,000 to $500,000 both cover a product with sign-in, billing and a dashboard. The difference is the hourly rate and how much of the SaaS machinery gets counted, so the next section prices that machinery on its own. What buyers paid, as opposed to what vendors ask, is further down. One survey figure to hold onto: GoodFirms (September 2026) puts 14.1% of custom software projects in the "small or MVP" band, under $30,000 and one to three months.

What a SaaS build includes that a plain web app does not, priced line by line

Once a product serves companies instead of individuals, each customer needs its own data, users, roles and settings, and usually its own bill. That's the extra work, and it's the part most cost guides fold into "backend development" without a number. Here's each piece with the figures vendors have put on it.

Two of those rows carry the money. Billing at $8,000 to $50,000 on its own explains most of the gap between a $5,000 web-app quote and a $40,000 SaaS quote. The two vendors disagree because they count different things: Appinventiv's line covers payment methods, billing rules and refunds, while Blackthorn's adds proration, tax and the dunning sequence for failed cards, which is where the hours go. The other expensive row has no price on it. Multi-tenancy costs little when it's designed in on day one and a rebuild when it's added after the tenth customer. A SaaS quote that doesn't mention it is a quote for a web app.

One more figure belongs here. GoodFirms' September 2026 survey puts the cost of scope growth at 10% to 25% of the project. Happy clients report the same. "Plan on an overage if you have a big scope," a founder who spent about $250,000 told Clutch in May 2026. "I had a little contingency in mind, and I used every bit of it."

Payment and billing fees: what Stripe, Paddle and Lemon Squeezy take

None of the ten SaaS cost guides we checked for this page prints a payment fee. Odd, because you pay it on every dollar of revenue for as long as the product lives. List prices as of October 17, 2026:

• Stripe charges 2.9% + 30¢ per successful domestic card transaction, plus 1.5% for international cards and 0.5% for manually entered cards.
• Stripe Billing, the subscription layer (plans, trials, proration, invoices, retries), adds 0.7% of billing volume on the pay-as-you-go plan, on top of card processing.
• Paddle, a merchant of record, charges 5% + 50¢ per checkout transaction.
• Lemon Squeezy, also a merchant of record, charges 5% + 50¢ per transaction with no monthly fee.

Put it on a real plan. A $50-a-month US card subscription on Stripe plus Stripe Billing costs $1.45 + $0.30 + $0.35 = $2.10, which is 4.2%, and the same subscription on Paddle or Lemon Squeezy costs $2.50 + $0.50 = $3.00, or 6%. On a $29 plan the fixed cents bite harder: about $1.34 (4.6%) on Stripe and $1.95 (6.7%) on a merchant of record. At 200 customers on the $50 plan, that's $420 a month against $600. Every month.

The extra 1.8 points buy you a seller of record: sales tax and VAT registration, filing and remittance sit with Paddle or Lemon Squeezy rather than with you, in every country you sell into. For a US company selling mostly to US businesses, Stripe plus a tax tool is usually the cheaper route. For a first product selling into many countries with a small team, the merchant of record earns its fee. Decide before the build. The billing code differs on each side, and switching later means rebuilding that row in the table above.

What hosting costs for an early SaaS, in dollars

Only three of the ten ranking SaaS cost guides put a dollar figure on hosting. Here are the list prices on October 17, 2026, for the stack an early SaaS runs on.

• Vercel Pro: $20 a month per seat, with $20 of usage credit included.
• Supabase Pro (Postgres, auth, storage): from $25 a month, 100,000 monthly active users included, then $0.00325 per user.
• Clerk (sign-in and organizations): Hobby $0, Pro $25 a month, Business $300.
• Render: a web service from $7 a month (512 MB) and a Postgres database from $19 a month (1 GB).

So a Vercel + Supabase + Clerk stack lists at $70 a month, and a Render web service + Render Postgres + Clerk Hobby stack at $26. Call it $25 to $75 a month at launch. That's before email delivery, error monitoring, a domain and any AI model bill. Two founders' own numbers land in the same place: "I'm at $800 MRR and spending around $150 on Cursor and hosting" (r/SaaS, May 2026), and an earlier founder expecting hosting "won't be more than $100 per month" (r/SaaS, 2023).

One vendor estimate sits far higher. Bitsens (May 2026) puts the recurring cost after launch at "$200 to $2,000 a month at the low end, $5,000 to $25,000 a month once you have real users and a real LLM bill". That page is about AI products, and the model bill is what moves the number. Hosting stays small until it doesn't. What grows is per-user auth, database size and model calls, and all three are usage-priced, so they rise with revenue rather than ahead of it.

What pushes a SaaS budget up: integrations, compliance and AI features

Integrations and compliance are in the table above: $1,000 to $15,000 per integration depending on who you ask, and 30% to 100% on top for HIPAA, SOC 2 or GDPR. The third driver is newer. Most SaaS scopes in 2026 arrive with an AI feature in them, and the vendors who price AI work separately give these bands:

• Space-O (October 2026): a thin product layer over OpenAI or Anthropic APIs, $5,000 to $15,000; retrieval over your own documents (RAG) with a vector database, $25,000 to $60,000; a custom or fine-tuned model, $100,000 to $150,000 and up.
• SF AI Labs (February 2026): basic API integration or a simple chatbot, $15,000 to $40,000 over 3 to 6 weeks; a custom RAG system or multi-model app, $40,000 to $120,000 over 8 to 14 weeks.

Two things temper those numbers. Continuum reports that in its builds "the AI feature is usually the smaller share of the budget. Accounts, billing, onboarding, admin, and monitoring are the larger share", which matches what we see. And Bitsens puts evaluation, observability and guardrails at 15% to 30% of the AI portion, which is the part a cheap quote leaves out and the part that keeps the feature from embarrassing you in front of a customer.

The model bill is smaller than most founders expect at the start. Take 1,000 active users making 30 requests a month at 2,000 input and 500 output tokens each: 60 million input and 15 million output tokens. At the October 17, 2026 list prices, that's about $270 a month on Claude Sonnet 5.5 or gpt-6.1-sol ($2 in, $10 out per million), and about $13.50 on Claude Haiku 5.5 or gpt-6-luna ($0.10 in, $0.50 out). Prompt caching and batch pricing lower both. Our AI MVP development page covers how we scope the AI part so the bill stays in that range.

Developer rates by region, and what 500 hours costs at each

The hourly rate is the biggest single reason quotes differ, and the published rate tables disagree with each other because they measure different populations. Directory averages (Clutch, GoodFirms) are dominated by offshore firms. Vendor tier tables and US shops' own rate cards sit far higher. Our custom software development cost guide goes through the same rate sources for projects that aren't SaaS; the short version is below.

Across 127 providers surveyed in early 2026 by Techreviewer, the most common band was $30 to $49 an hour (37.8%), and under 10% billed $100 or more. A quarter of the respondents were in India, which tells you who answers these surveys. Accelerance also reports that rates "dipped by single-digit percentages in all major outsourcing regions" in 2026.

Now multiply. One founder on r/SaaS was quoted "hourly at 150/hr and estimated 400-500 hours" for an MVP (October 2025). Take 500 hours as the unit. At $40 an hour, the middle of the India and Vietnam directory band, that's $20,000. At $75, the middle of the US directory band, $37,500. At $150, the floor of the US shops' own cards, it's $75,000, and at $250 it's $125,000. That's the whole "$5K to $100K" spread founders complain about, produced by one estimate and four rates.

A caution about the low end, from inside it. Deepsel's engineers are in Hanoi, and the senior ones aren't cheap by local standards: ITviec's salary report (2025 to 2026) has back-end developers' median monthly salary rising from 12.4 million dong at entry level to 54.9 million at high seniority, a fourfold gap. A $25-an-hour Vietnamese shop is paying juniors. The regional rate tells you where the team sits. It doesn't tell you who's on it.

What founders report paying for a first version

Vendor ranges are asking prices. Here's what people say they paid, from Reddit threads and Clutch reviews between 2023 and 2026, with the route they took. None of this is a dataset. It's the first-hand record, and the spread is the point. (Our MVP development cost guide covers the same first-hand record for MVPs of every kind, SaaS or not.)

That founder sent one brief to seven shops and picked the one that came back in 48 hours with a real scope document, which wasn't the cheapest. His line about it is the best advice on this page: "the proposal IS the test. how a shop scopes you is how they'll build for you." Two offshore studios had replied the same day with no questions and quotes of $9,000 and $11,000. He didn't reply. The cheap end of the market exists, and so does the reason it's cheap. If you want shops to send that brief to, our list of small software development companies for startups names some, with their rates and minimums, and our guide on how to choose a software development company has the rest of the checklist.

What Deepsel charges for a SaaS build

Three published prices, month-to-month. Which one you start on depends on what you already have, and the arithmetic is here so you can check it.

• Starting from nothing, nobody to own the technical side: $15,000 to $30,000. The Technical Leadership retainer is $15,000 a month and includes a fractional CTO who makes the architecture and roadmap decisions, plus the senior engineers who build. A typical startup MVP ships inside 1 to 2 months, so $15,000 to $30,000. A SaaS first version sits at the top of that window because billing, tenancy and roles are inside the scope. If the written estimate says it needs a third month, that's $45,000, and you know it before anyone starts. Then you step back to $0 a month, or keep an engineer on.
• You have a technical lead and need the hands: $4,000 or $8,000 a month. One dedicated senior engineer, half-day or full-time, with a demo every two weeks and a daily overlap window with US hours. Three months full-time is $24,000. The written estimate names the months.
• You have a prototype or a codebase: $3,000 first. A fixed one-week sprint: a full audit of product, code and architecture, the critical bugs and security holes fixed and shipped, and a plain-English scorecard and roadmap that's yours to act on with us or with anyone. It tells you which of the two routes above you're on, and how much of what you built survives. If the developer who built it has disappeared, our software project rescue page is the one to read.

Terms on every plan: month-to-month with 30 days' notice and no termination fees; a full money-back guarantee in the first 30 days; IP yours from the first commit under a US-jurisdiction agreement, with repos and servers in your own accounts; any engineer replaced within 7 days if not a fit; and a monthly Happiness Index where a month you score under 50 is refunded. The SaaS development service page lists what's inside the build, line by line, and the fractional CTO cost guide compares the retainer with hiring.

Why ours sits below the published agency bands: the engineers are in Hanoi on a flat retainer rather than a US hourly rate, the first version is scoped to what wins early customers, and we've done the accounts, payments and self-serve onboarding work before (on Clubloungery, where a club owner draws their own bookable lounges with no developer involved, and on eIAM, which signs in federal staff, cantonal partners and companies), so it isn't being figured out on your clock. The products we've shipped are on the projects page. Two honest limits. We're three senior people with a short client list and a waitlist when we're full, so a product that needs ten engineers next month belongs with a larger shop. And by the time you raise a Series A, investors will expect a CTO on the team. The retainer is the bridge to that hire, with diligence support included.

How to budget for a SaaS build

1. Write the first version as the smallest product a company will pay for, and put tenancy, billing and roles inside it. They cost little to design in and a rewrite to add after the tenth customer.
2. Price the hours and the rate in the same breath. A quote without a scope is a guess, and an hourly rate without a cap is, in one founder's words, "terrifying if you haven't" managed developers before. Ask for a fixed price against a written scope, or a flat monthly fee with a stop clause.
3. Budget payment fees as a share of revenue. 4.2% of every subscription on Stripe plus Billing, 6% on a merchant of record, more on cheap plans. Price your tiers knowing that.
4. Budget hosting at $25 to $75 a month to start and revisit it at a thousand users, when per-user auth and the database start to cost.
5. Hold back 30% to 40% for the eight weeks after launch. The shop that published its prices tells its own clients this, and satisfied Clutch reviewers say they used their contingency to the last dollar.
6. Insist on exit terms before the deposit. Repos, cloud accounts and the Stripe account in your name, access from day one, month-to-month, a documented handover. You learn a lot about a builder from what they're willing to put in the contract.

SaaS development cost: frequently asked questions

If you're budgeting a SaaS build and need a number against a written scope rather than a range, Deepsel's SaaS development service publishes its prices: $15,000 a month for the fractional CTO and the build team, $4,000 or $8,000 a month for a senior engineer, $3,000 for a one-week sprint on what you already have.
