The source behind every figure.
REMAXIA brings leases, payments, service charges, dunning and tax together under one roof — and tells you, for every amount, where it comes from. Developed and supported by INFONET Computer GmbH in Cologne.

Twelve solutions were examined in August 2026 — manuals, pricing pages, product reviews, plus our own subscriptions. What came out of it are not matters of taste but points at which a statement becomes open to challenge.
The industry standard carries an estimate flag — between the metering service and the software. With none of the twelve products does it reach the landlord. REMAXIA shows it, in five levels, and does not let an extrapolated value into the statement.
Splitting a utility bill that spans the turn of the year by days gives a figure that nobody challenges and that is still wrong: heating energy is used in January, not in July.
A cancelled invoice looks like any other in the files — and is otherwise allocated along with the rest. With utility suppliers, this means four-digit amounts and a statement that an objection will overturn.
January unpaid, February paid: then it is not the tenant who belongs in level 2, but the item. In the private landlord segment, none of the four widely used providers can do multi-level dunning — in a shared flat, REMAXIA calculates per person.
Base interest rate under § 247 BGB (German Civil Code) retrieved from the Bundesbank; nothing is calculated beyond the last known rate, and the gap is shown. Deposit interest under § 551 BGB over 21 years.
No provider publicly documents how it treats vacancy — on a question that affects every statement. In REMAXIA, vacancy is a separate participant in the denominator.
When a meter reading is entered, REMAXIA requires the source of the figure. Four levels go into the statement, one does not: “extrapolated” stays out. This means every item can still be explained years later — even when nobody remembers who took the reading back then.

No patchwork of spreadsheet, tax program and folder. A transaction on the account is entered once and takes effect everywhere: in the receivable, in the statement, in the dunning run and in Anlage V.
Amounts due, payments received, arrears, waivers, deposits — kept separately.
Document recognition showing where each value was found, allocability per item.
Import with duplicate protection; split combined payments across several receivables.
Allocation by floor area, persons, units, consumption — with source and accrual.
Lease with letterhead, graduated rent, shared flats, deposit, move-in and move-out.
Levels per item, fees, default interest to the day, history with reversal.
Anlage V per property, certificate under § 35a EStG (German Income Tax Act), depreciation (AfA) calculation.
Several owners kept separate, logo per client, permissions per user and area.

| Heating and hot water | Consumption 70/30 | Meter per unit | 9.600,00 | read |
| Gas supply 09/25–08/26 | Consumption | Heating degree days | 4.200,00 | accrued |

| Waste collection | Persons | 12 persons | 1.200,00 | Invoice |
| Invoice 2025-0042 (utility) | — | Cancellation detected | −5.000,00 | not allocated |
Every item shows key, basis and source — and the invoices that are not allocated are listed alongside, struck through and with the reason. So you can see on one sheet why the total looks the way it does.
“Not found” means: not found in the manual, pricing page and product review — not “does not exist”. Where another product is ahead, the table says so just the same.

Four occupants, one lease, three payments: REMAXIA calculates the arrears per occupant and sends a reminder to the one who has not paid. Level, fee, deadline and letter are tied to the item; the history stays alongside.

The usual providers charge monthly per unit: if you grow, you pay more for the same software, and with the market leader the limit is twenty units anyway. REMAXIA is licensed by edition — one-off, no tiered pricing, no upper limit.
