One job, three documents
Start every job with a quotation to the customer. When the customer accepts, record it as a sales order, and only then decide what you must buy to deliver it: parts, materials or a subcontracted service. Each purchase order to your own supplier then points back to that customer job, so the cost of the job and its selling price can be read side by side.
This order of work matters most for workshops that buy against a specific job, such as a vehicle repair in Sohar or a fabrication job for a site in Duqm. A purchase order written after the bill arrives is a record of what happened. One written before is a control on what you agree to pay.
A purchase order that settles arguments
Put on every purchase order the item, the quantity, the agreed unit price in rials to three decimals, the delivery point and the expected delivery day. Name the delivery point exactly, such as your Rusayl workshop or a customer site gate, because a driver with a vague address costs you a day. Add the customer order number so the supplier delivery note can be matched to the job.
Send the order in a language your supplier reads. TAQNIX ERP produces purchase orders in Arabic and English, so a supplier in Sohar and a manufacturer abroad can each read the same document in their own language. Keep one purchase order for one delivery, rather than a running order that nobody can close.
Matching the supplier bill
When the supplier bill arrives, compare it with three things: the purchase order, the delivery note and what physically arrived. Differences cluster in prices and quantities, and with three-decimal prices a slip is easy to make and easy to miss. Check the unit price to the baisa before paying, not only the total at the bottom.
For example, you order 40 units at OMR 2.450, which is OMR 98.000 plus 5% VAT of OMR 4.900, OMR 102.900 in all. The bill shows OMR 2.540 per unit, two digits swapped: OMR 101.600 plus VAT of OMR 5.080, OMR 106.680. The bill is OMR 3.780 above the order, and only a line by line check against the purchase order catches it.
Payment status and your own due dates
Every supplier bill has a due date set by the payment term you agreed, and a status that reads unpaid, partly paid or paid. Review the bills falling due in the coming week before you decide what to pay, and set them against what your own customers owe you. Paying early out of habit drains the account, and paying late makes a supplier reluctant to deliver your next urgent order.
Record part payments as they happen. A supplier in Sohar who is paid half now and half later should see two payments against one bill, not a new reference each time. That keeps the list of bills honest, and it keeps the conversation with the supplier short and friendly if a query comes up.
Repeat orders for regular customers
Regular customers, such as a factory buying the same consumables or a fleet owner bringing vehicles in turn, order the same things again and again. Start each repeat order from the last quotation and the last purchase order, then change only what moved: the price, the quantity or the delivery day. This is faster than retyping and keeps the wording identical for supplier and customer.
Re-check prices on every repeat order. A supplier price may have changed since last time, and a customer quotation built on the old price can wipe out the margin on the job. Treat a price change as a reason to speak to the customer before delivery, not after the invoice.
What to look at every week
Choose one fixed time each week, ask one person to prepare the list and keep the review short and practical. The aim is not a long report but a single view of what is late, what is due and what was forgotten. Anything on the list gets an owner and a day before the meeting ends: who calls whom, with which document, and by when.
- Purchase orders sent but not yet delivered
- Deliveries received with no supplier bill, and bills with no matching purchase order
- Supplier bills falling due in the coming week
- Customer orders accepted but not yet ordered from the supplier
- Regular customers who have not ordered for longer than usual
