Know the profit on every client. Close the month in a couple of clicks.
EIMIO turns the work recorded in your clients' Merit Aktiva into ready invoices, team payouts and margin on every client. Every job you have done reaches the invoice.
Requires a Merit Aktiva Pro or Premium package
EIMIO connects over Merit's API, which comes with the Pro and Premium plans. The Alusta and Standard plans have no API access, so they cannot be connected.
From work done to invoice and margin on every client
Four things EIMIO gives an accounting firm, in the order the money moves.
Profit per client — clear upfront
- You see what each client brings — before the contract is signed
- The team is paid only for work actually done
- Clients, services and contractors — in one system
All work reaches the invoice
- Extra services are added to the invoice automatically — at your rate
- No completed job gets lost or left unpaid
- Actual volume is checked against the package limits
Month-end closes in minutes
- Invoices for the whole portfolio — in minutes
- Invoice drafts are created right in Merit Aktiva — your numbers and dates
- You review and send invoices to clients in bulk
- Payout reports for contractors come with it
Margin under control
- Margin per client for the selected month
- Revenue, cost and profit — in one report
- Work and payouts — per employee or contractor
Margin on every client and which ones are worth more
You see which clients actually earn the firm money and which barely do. That is what you revisit tariffs on, rebalance the workload and decide where to put your team.
| Client | Fixed fee | Extra fees | Entries | Invoice | Contractor | Margin € | % |
|---|---|---|---|---|---|---|---|
| VESKI TRADE OÜ | €31550 incl. | €5418 entries | 68 | €369 | €36 | €333 | 90.2 |
| KASK & PARTNERID OÜ | €31550 incl. | €396132 entries | 182 | €711 | €264 | €447 | 62.9 |
| LUMEN STUDIO OÜ | €465flat fee | — | 254 | €465 | €410 | €55 | 11.8 |
The same pricing logic — a very different result. A flat-fee client you would never spot from the bank account.
A real month-end, start to finish
Connect a Merit Aktiva account, set the tariff, and run a bulk-invoice cycle — the whole thing in one run.
Three quiet leaks in every accounting firm
Pricing on estimates. Counting overage by hand. Paying the team by rules unrelated to the actual work. Each is a measurable monthly leak.
Revenue you've already earned — but never invoiced
Most clients post more transactions each month than their fixed package covers. That extra work is real time and real cost — done by your team. Without automated counting, it never lands on the invoice, and the firm quietly absorbs the margin.
A working day every cycle, spent on manual counting
Each client has a base monthly package. The work that exceeds it has to be counted, calculated, and added to the invoice by hand — every cycle, for every client. For a firm with twenty clients, that's a full working day each month, done by people who should be advising clients.
Per-client margin you can't actually see
Without a single dataset linking what you bill clients to what you pay your team, margin per client is a quarterly guess at best. The loss-makers only show up at year-end review — by then, the year is gone.
From first connection to bulk-issued invoices, in four steps
Configure once, per client. Then every month is a single click for the entire portfolio.
Connect each client's Merit Aktiva
One API key pair per client. About five minutes per account. EIMIO never writes to the client's books — only reads the general ledger.
Set the billing logic, once per client
Choose one of three tariff models. Define both what you bill the client AND what you pay the accountant — both, in the same configuration.
Define each client's invoice
Recurring lines (accounting plan, fixed fees, add-ons) plus a dynamic line that EIMIO populates from real transaction overage at invoice time.
Run month-end in one click
At cycle end, click Create Invoices. Every invoice lands in your firm's own Merit Aktiva — sequential numbers, correct dates, accurate totals.
Two rates on every tariff the whole model in one screen
What the client pays and what you pay the person who did the work — side by side on every tariff line. You see the margin the moment you price the work, and every month EIMIO checks it against the real ledger volumes. Your team is paid for jobs completed — so months close on time, without manual checks and chasing.
| Ledger group | Client | Team |
|---|---|---|
| Banksimple | €1.00 | €0.40 |
| Salesstandard | €3.00 | €1.20 |
| Fixed assetscomplex | €5.00 | €2.00 |
Fits the way you invoice today and grows with the firm
Three modes of adoption, configured per client. Start lightest. Add depth when you're ready.
Auto-invoicing only
Use your existing pricing. Bulk-issue every monthly invoice into your own Merit. No tariff configuration needed.
Fees + automatic overage
Keep your fixed monthly fee. Add a dynamic line that absorbs transaction overage automatically — calculated from the actual ledger.
Ledger-up pricing, both sides
Per-entry rates by complexity. Client billing AND accountant compensation calculated from the same dataset. Margin visible per client.
Three tariff models — flat, ranges, complexity-based
Tariff Plan 1 prices every GL entry equally. Tariff Plan 2 counts only the ledger ranges you choose — skip currency revaluations and double-entry technical rows. Tariff Plan 3 prices different ledger groups at different rates: bank entries cheap, sales entries higher, fixed-asset entries higher still.
Two pricing layers from one dataset
Every tariff carries two rates: Client Entry Fee (what you bill the client) and Supplier Entry Fee (what you pay your employee or contractor for the same work). The same general-ledger activity drives both — so margin per client and per team member becomes visible every month, in real numbers.
Invoices built from fixed lines + dynamic overage
Configure each client's recurring invoice once: Accounting Plan, fixed add-ons, recurring services. Add a dynamic line that EIMIO calculates automatically from actual transaction overage at invoice time. Fixed lines stay fixed; the overage line gets calculated for you.
Bulk invoicing — into your firm's own Merit Aktiva
Pick the reporting period. Pick the invoice date. Pick the starting invoice number. Tick All clients. Click Create Invoices. EIMIO writes every invoice directly into your firm's own Merit Aktiva via the API — sequential numbering, correct dates, accurate amounts. Open Merit, review, send.
What firm owners ask us first
Bills do not rise — they become accurate. Behind every line is the real number of entries from the ledger, and that is the evidence. Questions end at the report.
Start with bulk invoicing alone. Setup per client is about five minutes: name, API key and your tariff. First report the same day.
It measures the work, not the person — and pays for the result. Unfinished means unpaid, so months close on time.
Built around how an accounting firm actually operates
Three principles the product is built around — drawn from how accounting firms actually run their monthly cycles.
Read directly from the ledger. Nothing manual.
EIMIO fetches ledger activity directly through the Merit Aktiva API. No manual exports, no estimations, no missed entries. Every billable transaction is captured and priced exactly according to your tariff plans.
Set the rules once. Apply them every month.
Tariff plans and invoice templates are configured per client and stored permanently. Every cycle applies the same rules without reinterpretation. Consistent, repeatable, defensible — month after month, with no drift.
Nothing leaves your firm without your review.
EIMIO never sends invoices to clients. Every invoice is created in your own Merit Aktiva as a draft, ready for your team to review and approve before sending. Automation handles the calculation; your firm controls the final output.

Work you have already done belongs on the invoice.
Overage beyond the package rarely reaches the invoice — there is nobody to count it. EIMIO counts it per client and shows what that work costs the agency.
- Recover revenue from work already performed — you've just never had time to count and bill it.
- See per-client and per-team-member margin in real numbers — not estimates.
- Drop the manual month-end arithmetic — days of reconciling become one run across the whole portfolio.
- Build margin into every tariff from day one — visible per client, per team member, per month.
