Hidden ERP Costs Nobody Talks About
What an ERP really costs in 2026. Add-ons, modules, paid APIs, and promo prices that expire. With real data.
Key takeaways
- ERP prices can triple with add-ons: inventory, HR, and API access locked behind higher plans
- Promotional prices hide the real cost: some ERPs double their price after the first 3 months
- A freelancer needing invoicing + expenses + API can pay between 0 and 80 EUR/month depending on the software

The price you see on an ERP’s website is rarely the price you end up paying. What starts as “from 15 EUR a month” becomes 45, 80, or even 120 EUR once you add modules, add-ons, extra users, and the welcome discount expires.
This is not a conspiracy. It is the standard business model for business management software in Spain. And it works because most freelancers and SMEs do not discover the real cost until they have already spent weeks configuring the tool, at which point migrating feels more expensive than staying.
This article breaks down the hidden costs of the most popular ERPs in Spain in 2026. With real prices, not landing page numbers.
Hidden cost 1: Promotional prices that expire
Most Spanish ERPs offer an aggressive discount during the first months. The problem is that the real price is different.
| ERP | Promo price | Real price | Increase |
|---|---|---|---|
| Quipu Starter | 14 EUR/mo (annual) | 17 EUR/mo (monthly) | +21% |
| Anfix Basic | 4.99 EUR/mo (annual) | 5.99 EUR/mo (monthly) | +20% |
Many ERPs offer aggressive discounts during the first months that can double the real cost from the second year onward. Over a one-year subscription, the real average cost can be significantly higher than the introductory price.
Hidden cost 2: Modules that cost extra
This is where budgets go off the rails. Many ERPs sell the base at a reasonable price and then charge for features that an average business needs.
Anfix — volume scaling:
- 60 invoices/year on Basic (5 per month)
- API only on Premium: 79.99 EUR/month
- Full accounting from Business plan: 55.99 EUR/month (annual)
If you are a freelancer issuing 20 invoices per month and need API access for automation, Anfix costs at least 80 EUR/month. That does not appear in the “from 4.99 EUR” headline.
Quipu — limited OCR:
- Starter: 30 OCR scans/month
- API only from Solution: 25 EUR/month (annual)
- Analytics and projects: Premium only (49 EUR/month annual)
30 OCR scans seem like enough until you start accumulating fuel receipts, meals, supplies, and subscriptions. An active freelancer can generate 30 expenses in two weeks.
Hidden cost 3: Per-user pricing
Many ERP plans include a limited number of users. As your team grows, your bill grows with it.
| ERP | Base plan | Users included | Extra cost |
|---|---|---|---|
| Quipu Starter | 14-17 EUR/mo | 1 | Must upgrade |
| Anfix Basic | 4.99-5.99 EUR/mo | 1 | Must upgrade |
| Billin Pro | 12.50 EUR/mo | 3 | Unlimited plan (20 EUR/mo) |
| Frihet Free | 0 EUR/mo | 1 | Pro 15 EUR, Business 29 EUR |
| Frihet Pro | 15 EUR/mo | 3 | Business 29 EUR |
In some ERPs, moving from a single-user plan to a multi-user plan involves significant price jumps. It is important to calculate the real cost for your team size before committing.
Hidden cost 4: API as a premium feature
If you want to automate your business — connect your ERP with n8n, Zapier, Make, or your own application — you need API access. And many ERPs reserve it for their most expensive plans.
| ERP | Plan with API | Price |
|---|---|---|
| Anfix | Premium | 79.99 EUR/mo |
| Quipu | Solution | 25 EUR/mo (annual) |
| Billin | All plans (beta) | from 6.60 EUR/mo |
| Frihet | All plans | from 0 EUR/mo |
Anfix charges 80 EUR per month for API access. That is the price of a full plan on any other ERP. And without API, you cannot automate invoice generation, payment reconciliation, or syncing with other tools.
Frihet includes an open API and webhooks (14 events) on all plans, including the free one. Billin also offers API on all plans, though it is in beta.
Hidden cost 5: Bank reconciliation
Connecting your bank to the ERP so payments are automatically matched to invoices is one of the biggest time-savers. But it is not included on every plan.
Some ERPs include bank reconciliation on all plans but limit the number of bank connections per plan. If you have a personal account and a business account at different banks, you may need to upgrade.
Quipu includes automatic reconciliation only from Premium (49 EUR/month annual). Lower plans have manual reconciliation — which is basically the same as doing it in a spreadsheet.
The real cost: 3 typical profiles
Let us move past abstract numbers. Three real scenarios with monthly cost after the promotional period:
Freelancer (1 person, 30 invoices/month, OCR expenses, 1 bank)
| ERP | Plan needed | Real cost/month |
|---|---|---|
| Frihet Pro | Pro | 15 EUR |
| Billin Pro | Pro | 12.50 EUR + VAT |
| Quipu Starter | Starter | 14-17 EUR |
| Anfix Advanced | Advanced | 12.49-14.99 EUR |
For a freelancer with 30 invoices per month, Frihet’s free plan (10 invoices/month) is not enough, but the Pro plan (15 EUR/month) includes unlimited invoicing with all features.
Small business (5 people, 100 invoices/month, inventory, API)
| ERP | Plan needed | Add-ons | Real cost/month |
|---|---|---|---|
| Frihet Business | Business | — | 29 EUR |
| Quipu Premium | Premium | — | 49 EUR |
| Anfix Premium | Premium | — | 79.99 EUR |
Frihet Business includes inventory, API, and up to 5 users with no add-ons. Other ERPs in a similar price range may charge inventory as a separate module, pushing the real cost significantly higher.
Growing company (10 people, 300+ invoices/month, HR, inventory, API)
| ERP | Plan needed | Add-ons | Real cost/month |
|---|---|---|---|
| Frihet Enterprise | Enterprise | — | Custom |
| Quipu Premium | Premium | — | 49 EUR (no HR) |
| Sage 50 Standard | Standard | — | 109 EUR + VAT |
At this level, ERPs with add-on modules (HR, inventory) can exceed 200 EUR/month, approaching the cost of legacy software like Sage — which includes full accounting without charging for extra modules.
Why hidden costs exist
It is not malicious. It is a business model that works:
Acquire with a low price, monetize with add-ons. The entry price attracts the user. Once they have configured their company, imported their data, and trained their team, switching software has a high cost (time, risk, learning curve). Then the price goes up or paid modules appear.
This model generates predictable revenue but transfers the risk to the customer. You invest time configuring the tool before knowing what it will really cost.
The alternative is transparency: the price you see is the price you pay. All features included, with volume as the only variable.
How to evaluate the real cost of an ERP
Before choosing, calculate your real monthly cost with these questions:
Add it all up. That is your real monthly cost. Not the number on the landing page.
Frihet: price you see, price you pay
Frihet uses a different pricing model. No modules. No add-ons. No features locked behind plans.
- Free: 10 invoices/month, all features, 1 user, API included
- Pro (15 EUR/month): Unlimited invoicing, 3 users
- Business (29 EUR/month): Everything unlimited, 5 users, priority support
- Enterprise: Custom
It is not that Frihet is cheaper because it offers less. It includes inventory, OCR, dashboard, integrations, API, webhooks, and bank reconciliation on all plans. The difference is that it does not charge for them separately.
If you pay 29 EUR/month for Frihet Business, you pay 29 EUR/month. Next month, next year, and three years from now. No surprises, no fine print, no “starting from”.

FAQ
How much does an ERP cost for freelancers in Spain?
It depends on your needs. There are functional free options like Frihet (10 invoices/month). Paid plans range from 4.99 EUR/month (Anfix Basic, 60 invoices/year) to over 100 EUR/month with add-on modules. The real cost depends on the modules you need.
What are ERP add-ons?
Extra modules you pay for separately: inventory, HR, advanced bank reconciliation, API access, extra OCR scans, additional users. Some ERPs include everything in the base price; others charge for each feature separately.
Are ERP promotional prices reliable?
No. They are temporary prices that increase after the trial period. Many ERPs offer 50% off for the first 3 months, but the real price can be double. Always compare regular prices, not introductory offers.
Is it worth paying more for an expensive ERP?
Only if you use the extra features. If you only need invoicing, expense management, and tax compliance, an ERP at 15-29 EUR/month covers everything. If you need inventory, HR, multiple users, and full accounting, costs go up.
Does Frihet have hidden costs?
No. Frihet includes all features in every plan. The difference between the free plan and paid plans is only invoice volume (10/month free, unlimited on Pro and Business). No add-ons, no locked modules, no surprises.
