Construction patterns
Allocation, AP entry, and cash: where the job site loses the most time.
CONSTRUCTION · ACCOUNTS PAYABLE
Protheus AP document with cost-center allocation
Benefit invoices and recurring expenses stop depending on a monthly spreadsheet with dozens of allocations. Rules by supplier, periodic review, and controlled write-back in the ERP.
CONSTRUCTION · CASH FLOW AND TREASURY
Cash, intercompany, and a board view in the same cycle
Operations on SAP, Dynamics, and satellites need to consolidate cash and scenarios without printing a report. Automation connects banks, ERP, and the dashboard, with a manual adjustment when treasury asks.
Real examples
What we already design for construction
AP document entry, allocation, cash, and SAP/Dynamics stack based on real conversations in the sector.
Posting AP documents in Protheus
Branch, supplier, nature, cost center, and allocation filled from the invoice and the rules, with UAT before going to production.
Automatic allocation by supplier
Instead of a monthly spreadsheet with 25 different cost centers, fixed rules by supplier (e.g. 5% in CC X) reviewed every quarter.
Purchase order × AP document
When a PO exists, the flow reuses the fields; when posting is direct (internal legal entity), it keeps validation and avoids creating a useless extra order.
Utility invoices
Water, energy, telecom, and sewage: reading, validation, and posting in the ERP without typing invoice by invoice, common on job sites and developers.
Cash flow and intercompany
Funding, minimum-cash adjustments, and scenario comparison with write-back and a board dashboard, without depending only on Excel.
Credit and counterparty validation
Matching against Serasa, the tax authority, and internal databases to reduce fraud and speed analysis in B2B construction and materials operations.
Finance routines
The job site, allocation, and ERP change all day. Operations have to keep up.
When AP documents, cost centers, and cash live in different sources, construction becomes a manual queue.
Allocation that misses every month
Benefits and fixed expenses across dozens of cost centers. The spreadsheet changes, someone misses the percentage, and the posting goes wrong.
Manual AP document entry
Protheus or SAP ask for branch, nature, cost center, and allocation. Typing is slow and inconsistent between job-site and back-office teams.
SAP + Dynamics + 40 satellites
Finance ERP, credit CRM, and dozens of surrounding systems. Homegrown integration without governance becomes a risk.
Cash and job site disconnected
Treasury closes in a spreadsheet while the job site generates spend all day. Without a single view, close slips.
Pipeline
Capture → Validate → Post → Audit
An accounts payable and cash flow for construction, with prioritized exceptions and ERP write-back.
Capture
NF-e, utility invoices, and job-site documents structured without typing.
Validate
PO, allocation, cost center, and approval limit. Exceptions go to human review before the ERP.
Post
Write-back to Protheus, SAP, or Dynamics with the AP document ready.
Audit
Cash dashboard, allocation history, and a trail for the job site and back office.

Frequently asked questions about financial automation for construction
Do you replace Protheus or SAP?+
No. Abstra is the financial automation layer for construction and real estate development between documents, allocation and cash rules, and the ERP the company already uses, such as Protheus, SAP, or Dynamics. Posting stays in the current system, with traceability.
Can you set allocation by supplier?+
Yes. In accounts payable automation for construction companies, allocation rules live in the flow (with permission for who can edit), applied on the AP document and reviewed periodically. That reduces the monthly allocation spreadsheet by job, cost center, or supplier.
What about cash flow / treasury?+
Yes. You can consolidate balances, intercompany, and cash-flow scenarios with a board dashboard, keeping a manual adjustment when treasury needs it. Automation feeds the cash view without depending only on spreadsheet exports.
Where should a construction operation start?+
With the AP document and allocation, where operational error hurts AP the most, or with cash flow if the board pain is visibility and close. On job sites and multi-entity groups, those two fronts usually bring the fastest return.
Bring the allocation or AP document that gets stuck the most. We'll build it with your team.
In construction, cost-center rules, ERP write-back, and auditable cash are the baseline. A chat that “guesses” is not enough.
