DATEV analysis and planning: the tools compared

The short answer

If you only read one section, read this one. The rest of the article shows the working.

• You want DATEV data readable, with drill-down to the entry → helu.io
• You want DATEV plus bank data in a liquidity plan → finban
• You want DATEV data projected forward with drivers on top → Foreqast

None of those sentences is a ranking. These products answer different questions, and the wrong one bought well is still the wrong one.

How this comparison works

We are Foreqast, so read the last-but-one section first if you want to know where the bias would be. The rule we hold ourselves to here: every claim about another product comes from that vendor's own site or from public review directories, checked on 24 August 2026, and every tool gets a verdict saying when it beats us. Where a vendor does not publish a price, this article says so instead of guessing.

What we do not do is score these tools out of ten. A weighted table can be made to say anything, and the weights are always the author's. Instead each product gets a plain description of what it is for, what it does well, where it stops, and the kind of company it fits.

The tools at a glance

What separates these products is not the length of their feature lists. It is where the future numbers come from — because that decides which questions the tool can answer at all.

How these tools build a forecast

Almost every difference further down comes back to this. A tool can only tell you about the future in the language it builds the future in.

From the books, looking back

The accounting data is made readable: cost centres, contribution margins, month against month, budget against actual. This is reporting rather than forecasting, and it is genuinely the more valuable half for a company that does not yet know what its last quarter cost. It does not become a plan on its own.

From payments and invoices

Every expected in- and outflow is a dated line: this invoice on that day, this contract every month, this supplier on those terms. It is precise where the future is already contracted, and it is the right model for a business that mostly bills projects and retainers. It gets laborious where the future is not a list of payments but a pattern — a shop's orders, a product's subscribers.

From drivers

Revenue is a formula rather than a line: orders times basket size minus refunds, subscribers times price minus churn, booked hours times rate. Change one input and everything downstream — margin, cash, runway — recalculates. It takes more thought to set up than a bank connection, and it is the only one of the four that answers "what happens if" without a second spreadsheet.

The tools in detail

Each product on its own terms: what it is, what it is genuinely good at, where its scope ends, what it costs, and the company it suits best.

helu.io

Reporting and controlling on top of DATEV: live reports, cost-centre analysis down to the individual entry, and budget against actual. (website)

What it does well

• A DATEV interface that turns bookkeeping into readable reports without an export ritual.
• Drill-down to the individual entry per cost centre — the thing spreadsheets never do well.
• Budget against actual and dashboards a whole team can share with the accountant.

Where it stops

• Its centre of gravity is what already happened; planning ahead is not the same discipline as reporting on closed periods.
• Pricing is on request rather than on the website.

Price: On request; a free trial is offered.

Best for: Companies on DATEV that want their numbers readable and current — cost centres, budget against actual, one shared view with the accountant — rather than a forward model.

finban

Liquidity planning for project-driven businesses: bank and invoice data become a daily cash plan, with scenarios and an assistant that flags irregularities. (website)

What it does well

• Direct bank connections — the vendor names more than 3,000 institutions — so actuals arrive without exports.
• Contract management and scenarios sit in the same tool as the plan.
• Published pricing and a trial without a credit card, which is rare in this category.
• Hosted in Germany on ISO-certified servers, which matters to a lot of buyers here.

Where it stops

• The plan is built from payments and invoices; there is no driver model that turns orders or subscriptions into revenue.
• That means a price change or a bigger ad budget has to be entered as an assumption rather than costed through.

Price: Published; listings put the Starter plan at €26.25 a month billed annually (one bank account, one user) or about €36 billed monthly, with Business at €48.75 and Pro at €90. Free trial, no card required.

Best for: Agencies, SMEs and startups with project or invoice-driven revenue that want bank-accurate liquidity, contracts in the same place, and a price they can read on the website.

Foreqast

A forecast built from your accounting plus the drivers your revenue actually runs on — orders and basket size, subscriptions, tracked hours — with a simulator for testing a decision before you make it.

What it does well

• Revenue is a formula, not a trend line: change a driver and the forecast recalculates through to margin and cash.
• Cash and profit come out of one model, with margin in total and per unit beside them.
• Decisions sit next to the plan — a hire, an ad budget, a cancellation — and can be compared with and without.
• Shop, billing and time-tracking data feed the drivers, so the plan does not need weekly upkeep.

Where it stops

• It builds on your accounting rather than on bank connections, so it is not a treasury tool for many accounts and currencies.
• No consolidation across a group of companies today; multi-entity is the partner plan's territory.
• It is in early access, so the customer list is short and some things are still on the roadmap.

Price: €39, €149 and €399 a month, published; partner plans from €800 on request. Free on every plan during early access, no card.

Best for: Shops, agencies and small SaaS teams whose revenue moves with something countable — orders, subscriptions, booked hours — and who want to cost a decision before making it rather than watch a balance.

What to check before you buy

Questions worth asking any vendor on a demo call, including us. The answers separate these tools faster than any feature list.

How does the data get out?

A direct connection beats an export. Anything somebody exports is stale between exports.

Are accruals read correctly?

Entries, accruals and open items mean different things for cash and for profit.

Does your accountant stay in the loop?

The tool should read your bookkeeping, not replace it — otherwise you have two truths.

Does it go beyond reporting?

Only drivers and due dates turn DATEV data into a plan.

When Foreqast is the wrong tool

A comparison written by one of the products in it owes you this section, so here it is without hedging.

• You only want the annual accounts — that stays with your accountant.
• You need receipt capture and coding — that is bookkeeping software.
• You don't use DATEV at all — Foreqast also reads the DATEV-format exports from lexoffice and sevdesk, and plain CSV.
