Project Billing

12 Sep. 2023 | MARIProject

Efficient project billing and posting, even with down payment variants

Project billing and posting are quite time-consuming tasks, because even in typical projects at cost or at fixed price, costs for items, services or travel expenses have to be accounted for and correctly allocated. Accounting becomes more demanding as soon as down payments come into play, which may also become relevant for tax purposes at different times.

How much effort do you put into making payment claims for projects or settling warranty retentions? Are taxes due automatically taken into account in your system after receipt of the down payment?

Typical project billing

With MARIProject, you can flexibly invoice typical projects at fixed price or at cost, with services of regular employees or freelancers, at different prices, with weekend or night surcharges or time limit, with discounts, billing by due date, milestone, etc.

Recorded project hours can be completely or partially approved for billing. Accordingly, they are also taken into account in evaluations.

Another special feature: Due to the integration in SAP Business One, all invoices from MARIProject are automatically posted.

Project billing with special requirements

Special forms of billing are also flexibly supported, such as

– retentions

– payment claims

– advance payments (retainers)

– down payments

– final invoice

– pro rata billing, even with accrual in previous months or

– subcontracting.


All forms of project billing can be flexibly set for each project. During billing, costs and revenues are automatically assigned to the project and the business unit.
