For US-project budgeting in 2026, this guide compares different kinds of estimates. Basic CRM figures of $24,000–$45,000 and standard CRM figures of $54,000–$112,000 are attributed vendor estimates, not market-wide statistics or Rvion quotes. The $25,000–$60,000 accounting/invoicing and $50,000–$150,000 custom B2B ordering ranges are provisional planning assumptions, not verified US-specific benchmarks. A real budget requires a defined scope and written quotes.
The short version
| Product | Indicative planning range (USD) | Indicative timeline |
|---|---|---|
| Basic CRM (contacts, tasks, simple reports) | $24,000–$45,000 | 8–12 weeks |
| Standard CRM (automation, integrations) | $54,000–$112,000 | 12–20 weeks |
| Enterprise CRM (AI, deep integrations) | $150,000–$360,000+ | 20–40 weeks |
| Small accounting / invoicing app | $25,000–$60,000 | 8–14 weeks |
| Mid-level accounting platform | $50,000–$120,000 | 5–8 months |
| Advanced accounting platform | $120,000–$300,000+ | 8–12 months |
| Basic B2B ordering storefront | $15,000–$30,000 | 2–4 months |
| Custom B2B ordering platform (contract pricing, ERP sync) | $50,000–$150,000+ | 4–9 months |
| B2B marketplace (multi-vendor) | $50,000–$250,000+ | 4–9 months |
GMWARE's 2026 CRM guide supports the three CRM rows. Hidden Brains publishes different bands, showing vendor estimates are not interchangeable. The accounting and ordering rows remain illustrative assumptions, not verified US market data. Yo!Kart instead quotes a marketplace MVP at $30,000–$50,000+ and an advanced marketplace at $120,000–$200,000+; that is a different scope.
Why these products are often built with Django
CRMs, accounting tools and B2B portals are data-heavy apps: users and roles, records, permissions, forms, reports and integrations. Django ships much of this plumbing: authentication, an admin panel, a database layer, migrations and common security protections. A small team reaches a testable version sooner, and the same codebase can grow. That is why Python and Django are a common choice for internal tools, SaaS and B2B platforms. It is a technology choice, not a price guarantee.
What changes the price
- Users and roles. One role is cheap; buyers, sellers, staff and admins multiply screens and rules.
- Integrations. Third-party services and ERP or procurement links add effort; ask for a separately scoped estimate for each.
- Buyer onboarding. Business verification, credit terms and multi-user accounts add work that a simple storefront estimate may omit.
- Payments and payouts. Split payments and commissions are essential in marketplaces and costly to get right.
- Mobile. A companion app is a separate scope; do not assume it is included in the web build.
- Compliance. Regulated data can require additional design, controls and specialist review; do not apply a universal percentage uplift.
Costs after launch
Budget hosting and tooling separately for actual traffic, storage and provider choices. GMWARE suggests annual maintenance at 10–20% of build cost; treat this as that vendor's planning guide, not a fixed rule.
Freelancer or agency?
Compare actual freelancer and agency quotes for the same deliverables. A senior freelancer may suit a focused first version; an agency may offer broader capacity. Hourly rate alone does not establish the total cost or guarantee delivery.
Custom or off-the-shelf?
Off-the-shelf CRMs and accounting tools charge per user per month and are the right start for most small teams. Custom starts to pay off when your workflow is unusual, your volume is high, or you need integrations a product cannot offer. For B2B commerce, compare the provider's current plan, integrations and transaction fees with the full cost of a custom build. Shopify Plus and BigCommerce have different commercial terms; there is no universal monthly price or break-even point.
How to get a quote you can trust
- Write a feature list by role: who does what, on which screen.
- List every integration and the system on the other side.
- State data volumes and the compliance rules that apply.
- Ask each vendor for itemized estimates and a discovery phase.
- Put code ownership, repository access, staging and a maintenance plan in the contract.
FAQ
How much does a custom CRM cost for a small business? GMWARE's indicative basic-build range is $24,000–$45,000; adding automation and integrations moves it toward $54,000–$112,000.
How much does it cost to build an invoicing app? Our unverified planning assumption for a focused invoicing or accounting app is $25,000–$60,000 for a focused first version, plus yearly upkeep.
What does a B2B ordering platform cost? Our provisional planning assumption for a basic B2B storefront is $15,000–$30,000; a custom platform with contract pricing, account hierarchies and ERP sync is more like $50,000–$150,000+.
Can a freelancer build this? A senior freelancer can build a focused first version of any of these, especially with a clear scope. Larger platforms need a team.

Sources checked 12 October 2026: the linked GMWARE, Hidden Brains and Yo!Kart guides are vendors' estimates, not an independent US pricing survey. Unverified accounting and ordering assumptions require a project-specific quote. Django's included tools are described in its official overview.
