Workflow example

1

Create a work sheet

Create a new work sheet for billing:
curl -X POST https://mantis.peisol.com.ec/api/workorders/sheets/create/ \
  -H "Content-Type: application/json" \
  -d '{
    "project_id": 5,
    "date": "2025-03-01"
  }'
2

Add line items

Line items are typically created automatically based on project resources, or can be added manually through the UI.
3

Update quantities

Adjust days/quantities for each line item:
curl -X PUT https://mantis.peisol.com.ec/api/workorders/sheets/detail/1/days/ \
  -H "Content-Type: application/json" \
  -d '{"days": 5}'
4

Liquidate the sheet

Change status to LIQUIDATED when ready for billing:
curl -X PUT https://mantis.peisol.com.ec/api/workorders/sheets/update/ \
  -H "Content-Type: application/json" \
  -d '{
    "id": 1,
    "status": "LIQUIDATED"
  }'

​
Best practices

Series codes are automatically generated in the format PSL-PS-YYYY-NNNN where:
  • PSL: Company prefix (PEISOL)
  • PS: Document type (Project Sheet)
  • YYYY: Current year
  • NNNN: Sequential number
Tax is automatically calculated as 15% (IVA) of the subtotal. The total is subtotal + tax_amount.
Follow this workflow:
  1. IN_PROGRESS: Sheet is being created/edited
  2. LIQUIDATED: Sheet is ready for invoicing
  3. INVOICED: Sheet has been invoiced
Use reopen endpoint to move back to IN_PROGRESS if needed.
