ERPNext is the open-source ERP most often shortlisted by small and mid-sized companies that have outgrown accounting software but do not want a per-user licence bill. The appeal is obvious: the software is free. The misunderstanding is just as common: the project is not. This guide sets out what an ERPNext implementation costs and how long it takes for a company of 10 to 100 people, using vendor-published figures where they exist and honest descriptions of the drivers where they do not.
What does ERPNext itself cost in 2026?
Nothing, in licence terms. ERPNext is published by Frappe Technologies under the GNU General Public License v3, as stated in the project repository on GitHub. There is no per-user fee, no module fee and no edition split: accounting, selling, buying, stock, manufacturing, projects, CRM and the rest are all in the one open-source product. The current major release is version 16, which Frappe announced in early 2026 with custom financial report templates, a consolidated trial balance across subsidiaries, an MRP workflow, inward subcontracting and stock reservation among the headline changes.
What you pay for is everything around the software: somewhere to run it, someone to set it up, and the time of your own people. Our ERPNext listing scores the product itself; this guide is about the project.
The open-source ERP whose free tier is the entire product
Best for: Cost-conscious SMEs with in-house technical capability — or a good implementation partner — that want full ERP breadth without per-user licence costs.
What does hosting cost: Frappe Cloud or self-hosting?
You have three realistic options, and the choice changes both the monthly bill and who carries the operational risk.
| Option | Published price, as of September 2026 | What you are responsible for | Best for |
|---|---|---|---|
| Frappe Cloud — shared site plan | From $5/month (frappe.io) | Your configuration and data; Frappe handles upgrades, backups and monitoring | Pilots, very small teams, evaluation |
| Frappe Cloud — dedicated server | From $40/month (frappe.io) | As above, plus choosing the server size | Most 10–100 person production sites without an operations engineer |
| Self-hosted on your own VPS or hardware | No Frappe fee; you pay your server provider | Everything: operating system, Docker or bench, MariaDB, backups, TLS, updates, security | Teams with a capable administrator, or data-residency rules that require it |
Frappe Cloud is run by the company that maintains ERPNext. Its pricing page lists managed upgrades, off-site backups, multi-region hosting, custom domains and SSH access on site plans, a 14-day free trial, and an optional "Product Warranty" support arrangement with priority SLA on servers. Prices scale with compute and storage, so "from" is the floor, not the typical bill: a production site for 30 users with attachments will sit on a larger plan than the entry tier.
Self-hosting removes the hosting fee but replaces it with labour. Our self-hosted install guide walks through the Docker route and is candid that 2 GB of RAM is the floor and 4 GB is comfortable for a small production site. The install is the easy part. The cost is the monthly discipline afterwards: tested backups, version updates, certificate renewals and someone who notices when the disk fills. If nobody on your team will own that, the $40-a-month tier is cheaper than the first outage.
A three-year total cost comparison therefore has two lines for Frappe Cloud (plan plus any support add-on) and three for self-hosting (server, administrator time, and the cost of downtime you are implicitly insuring yourself against). For most firms under 100 people the managed route wins on total cost once administrator time is priced honestly.
What drives the implementation cost?
Frappe's own pricing page is explicit that it does not provide implementation directly: buyers self-implement, buy a partner "starter pack", or hire from its partner network. Whichever route you take, five things decide the size of the bill.
- Modules in scope. Accounts, selling, buying and stock is a very different project from one that adds manufacturing with bills of materials, projects with timesheets, and HR with payroll. Each module brings its own masters, workflows, permissions and training.
- Customisation. Custom fields, print formats, workflows and simple scripts are routine and upgrade-safe. Custom apps and changes to core behaviour are development projects with a maintenance tail. The cheapest customisation is the one you decide to live without.
- The state of your data. A clean item list with consistent units of measure migrates in a day. Three spreadsheets with duplicated customers, free-text item names and no opening stock valuation can consume weeks — mostly your team's weeks.
- Integrations. E-commerce, payment gateways, banks, a separate payroll provider, e-invoicing platforms. Each integration needs building or configuring, testing and someone to own it when it breaks.
- How much your team does. A company that assigns an internal project owner, cleans its own data and trains its own second wave of users buys far fewer consultant days than one that wants everything done for it.
We have deliberately not printed day rates or "typical project" totals. Partner pricing varies widely by country and is rarely published, and we would rather explain the drivers than repeat numbers we cannot source. Ask any implementer for a fixed fee per phase with written scope, and compare proposals on scope rather than headline price.
How long does an ERPNext implementation take?
The table shows typical planning ranges. They assume a standard configuration with light customisation, a named decision-maker on your side with a few hours a week, and master data your team can clean inside the first month. They are planning ranges, not guarantees.
| Company size | Typical scope | Typical range to first go-live |
|---|---|---|
| 10–25 staff | Accounts, selling, buying, basic stock; one company, one warehouse | 6–10 weeks |
| 25–60 staff | The above plus multi-warehouse stock, projects or light manufacturing, one or two integrations | 3–5 months |
| 60–100+ staff | Multi-company or multi-branch, manufacturing with BOMs, HR and payroll, custom reports | 5–9 months, phased |
Two things move a project along the range more than anything else: how quickly process decisions get made (who approves purchase orders, how stock is valued, which price list wins) and whether go-live is aligned to a clean accounting cut-over such as a month or quarter end.
What are the phases of an ERPNext project?
A sound project has the same shape regardless of size.
- Assessment and design. Fit/gap against your processes, chart-of-accounts design, a migration inventory and a hosting decision. This is where a bad fit should be caught — before money is spent on configuration.
- Core configuration. Company, fiscal year, chart of accounts, taxes, warehouses, item groups, price lists, users and roles.
- Data migration, rehearsed. Masters first, then opening balances and open documents. At least one full rehearsal into a test site before the real cut-over.
- Training and user acceptance. Each role runs its own real transactions on a copy of the real data and signs off.
- Cut-over and parallel run. Opening balances loaded and reconciled; a short overlap where key figures are checked against the old system.
- Stabilisation, then the next phase. Two to four weeks of close support, then manufacturing, projects or HR as a separate, scoped phase.
Our migration checklist covers the data and cut-over phases step by step.
What are the biggest risks, and how do you reduce them?
- Nobody owns master data. The item list and customer list need a named owner with authority to merge, rename and delete. Without one, go-live slips every week.
- Replicating the old system. Rebuilding every quirk of the previous software through customisation costs the most and ages the worst. Start from ERPNext's standard flow and customise only where the business genuinely differs.
- Big-bang scope. Going live on everything at once multiplies risk. Accounts and core trading first; the rest in phases.
- Unmaintained self-hosting. A server nobody patches or backs up is a liability that appears on no budget line until it fails.
- Regional compliance assumed, not checked. UAE VAT settings ship with ERPNext, and the UAE starts mandatory e-invoicing in phases from January 2027. Saudi ZATCA Phase 2 integration relies on third-party apps from the Frappe Cloud Marketplace; ZATCA's Wave 24 brought businesses above SAR 375,000 in VAT-able revenue into scope by 30 June 2026. Qatar has no VAT as of September 2026. Confirm your own obligations and the app's version support before committing.
Who should not implement ERPNext?
If you have fewer than about 15 people and your pain is bookkeeping, not operations, good accounting software such as Xero plus a CRM will serve you better for less. If you are a group with many legal entities across several tax regimes, look at Dynamics 365 Business Central or the tier above it; our three-way ERP comparison and ERP selection guide cover that ground. And if you want a single vendor contractually accountable for software and implementation together, an open-source product supported by a partner network is structurally not that.
How we evaluated
Digital4All has installed and used ERPNext hands-on — the install is documented in our guide and video — and our listing is scored on that basis. Hosting prices, the licence, the version 16 feature list and the partner-network description come from frappe.io and the ERPNext repository on GitHub, read on 18 September 2026. The two Frappe pages we read show different entry prices for servers; we quote the Frappe Cloud pricing page. Regional tax dates come from ZATCA and UAE Ministry of Finance announcements as reported in September 2026. Timeline ranges are our planning judgement under the stated assumptions, not measured averages, and we publish no implementation fee figures because we found no reliable public source for them.
What should you do next?
If you would rather have these decisions made with someone who does this for a living, our ERPNext implementation and rescue service starts with the ERPNext Readiness Assessment: a fit/gap against the modules you need, a migration inventory, a self-host vs Frappe Cloud cost model and a go/no-go, in ten working days. The fee is fixed and quoted in writing after a free 20-minute call — and the honest answer is sometimes "not yet".
