The verdict in three sentences
For an SMB in Amsterdam issuing 400 to 1,500 invoices a month, automating with Make or n8n removes most re-keying between CRM, quotes and accounting for an integration budget of EUR 3,000 to 12,000 excl. VAT. Licences stay modest, EUR 10 to 30 a month for Make and EUR 20 to 50 a month for self-hosted n8n, but fragility grows with the number of scenarios. Beyond about twenty scenarios or complex billing rules, custom development becomes sturdier and cheaper to maintain.
Make, n8n or custom: 2026 comparison
The typical SMB flow: a quote signed in the CRM, an order re-keyed into the invoicing tool, an invoice exported by hand to accounting software, then reminders sent from a mailbox. Each manual step costs time and creates 1 to 3% errors.
| Criterion | Make | Self-hosted n8n | Custom development |
|---|---|---|---|
| Licence or hosting | EUR 10 to 30 / month (10,000 to 40,000 operations) | EUR 20 to 50 / month (server) | EUR 50 to 150 / month (server, monitoring) |
| Initial agency integration | EUR 3,000 to 8,000 | EUR 4,000 to 12,000 | EUR 15,000 to 40,000 |
| Setup time | 2 to 4 weeks | 3 to 6 weeks | 6 to 12 weeks |
| Data | Hosted by Make (EU available) | On your own EU server | On your server |
| Comfortable volume | Up to 1,000 invoices / month | Up to 5,000 invoices / month | Unlimited |
| Weak point | Per-operation cost climbs | Server maintenance needed | Initial investment |
| Switch threshold | Over 20 scenarios | Over 30 scenarios or heavy business logic |
Make suits teams that want to start fast without a server. n8n appeals to finance directors who care about data sovereignty and fixed costs, since executions are not billed when self-hosted.
The scenarios that pay off most
| Scenario | Connected tools | Integration cost excl. VAT | Time saved per month |
|---|---|---|---|
| Signed quote to deposit invoice | CRM + invoicing tool | EUR 800 to 1,500 | 6 to 12 hours |
| Invoice to accounting entry | Invoicing + accounting software | EUR 1,000 to 2,500 | 8 to 16 hours |
| Automatic reminders D+7, D+15, D+30 | Invoicing + email | EUR 600 to 1,200 | 5 to 10 hours |
| Payment reconciliation | Bank + accounting | EUR 1,500 to 3,500 | 10 to 20 hours |
| Peppol / UBL e-invoicing | Invoicing + access point | EUR 1,500 to 4,000 | Public sector and EU compliance |
| Receivables tracking sheet | Invoicing + spreadsheet or BI | EUR 800 to 2,000 | 3 to 6 hours |
E-invoicing is spreading across the EU under the ViDA package, and Dutch public buyers already require Peppol UBL invoices. Your automations should route through an accredited access point and produce UBL or Factur-X formats: this is often what triggers the project.
Limits to know before starting
A no-code scenario breaks silently when an API changes or a field is renamed in the CRM. Plan a failure alert and a monthly check, 2 to 4 hours of maintenance per month, or a contract at EUR 150 to 400 a month. Complex rules (tiered discounts, multi-entity recharging, intra-EU VAT) become unreadable in a visual editor: that is where custom code regains the edge.
Mini case study
Sophie, finance director of a 45-employee distribution SMB in Amsterdam, issues 900 invoices a month. Two accountants spend about 3.5 days a month on re-keying and reminders, 42 days a year. With 5 n8n scenarios (quote to invoice, accounting export, reminders, reconciliation, receivables tracking) integrated for EUR 7,500 and a EUR 35 monthly server, she recovers 3 days a month. At a loaded cost of EUR 320 per day, the gain reaches EUR 11,500 a year, plus a monthly close brought forward from D+8 to D+4. Payback: 8 months. Average payment time also drops by 6 days thanks to automatic reminders.

FAQ
Make or n8n for a 30-employee SMB?
Make if you have under 10 scenarios and no hosting constraint. n8n once data must stay on your own EU server or volume exceeds 40,000 operations a month.
Is automation compatible with e-invoicing rules?
Yes, as long as your scenarios connect to an accredited Peppol access point. Count EUR 1,500 to 4,000 for that connection.
Do we need an in-house developer?
Not for Make, an admin profile trained in 2 days is enough. For self-hosted n8n, plan a provider for server updates, about EUR 150 a month.
When should we move to custom code?
Beyond 20 to 30 scenarios, 5,000 invoices a month or complex pricing rules. Budgets start around EUR 15,000.
How soon do the first gains appear?
The first two scenarios are live within 2 weeks and already save 10 to 20 hours a month.
