The tool is fine until your volume changes

A Dutch freelancer posted that his bookkeeping in MoneyMonk was working fine — until he switched from fixed-price projects to subscriptions. Monthly invoices instead of annual ones. Purchase invoices that needed to be booked manually, at increasing volume.

He wanted to automate the import from his own system. MoneyMonk had no API. Support said there were no short-term plans for one.

He asked the community: stay and accept the manual work, switch to Moneybird now, or wait until things get bigger?

Both founders replied.

The MoneyMonk founder confirmed the limitation honestly: the API is coming in 2026, but not immediately, so for his situation it makes sense to consider alternatives.

The Moneybird founder explained what switching would actually solve — and flagged what it wouldn’t: credit card integration is still difficult regardless of platform, and payroll needs separate software anyway.

What strikes me about this story is that the tool didn’t break. MoneyMonk still does what it did before. The business model changed, and suddenly the same tool that was perfectly adequate became an obstacle.

This happens more often than people plan for. A tool without an API is a tool with a ceiling. That ceiling is invisible when your volume is low and becomes very visible when it isn’t.

It’s worth knowing where that ceiling is before you hit it.

The question to ask when choosing bookkeeping software isn’t just “does this do what I need today?” It’s “what happens if my invoice volume triples?”

If the answer is “we’d have to migrate,” that’s worth factoring in at the start.
