A small company has largely worked for farmers in a small municipality in the repair and service of tools and equipment. Maintenance of cars, tractors and other equipment for farmers in the countryside, which has been the main work since the establishment of the company in 2014. Other various projects for municipalities such as garbage collection, laying footpaths, digging ditches and laying electric cables and heating pipes. The company also operates a staffing agency to take care of unloading ships ashore and loading the ships with products at ports, it also takes care of servicing and repairing fish processing machines and equipment.

Recently, a company has offered to become a subcontractor in a large project within the municipality, but it has been pointed out that first it needs to adjust the way invoices are made, make them more understandable and accurate and send them to customers much earlier.

There are several suppliers, but it is not the main thing who they are, but that they all give payment terms ranging from 30 to 90 days because the company is reliable and always pays on time.

The company has a full-time finance manager and bookkeeper, as well as an aftersales manager and a foreman who take care of orders and approve invoices depending on how big the amount is, otherwise the aftersales manager has to approve and he has to get the finance manager's approval if the amount is not within the limits. The company must demonstrate work processes for collecting invoices that meet general quality requirements.

What should the BPMN Standard process on a flow chart look like in terms of customer solvency, agreeing that invoices are set up correctly and giving a payment deadline of up to 30 days for those who pass the payment assessment, also how to issue a warning to those who do not pay on time or a reminder or for those who do not pay at all.

The company needs to fix the billing processes and set it up in BPMN standard flow form in order to get the project and be able to expand.

What does such a BPMN standard flow chart look like?
