Use this guide to set up material costs, supplier prices and markups, then check that a quotation achieves the intended profit margin.
Applies to: staff maintaining stock records, material plans and manufacturing quotations.
| Control | Purpose |
|---|---|
| Purchase Unit Cost | The cost for one purchase unit on the stock record. |
| Conversion Factor | The number of stock units represented by one purchase unit. |
| Stock Unit Cost | Purchase unit cost divided by the conversion factor. |
| Stock Markup % | A default copied onto material lines when a stock item is selected. |
| Material line % Markup | A percentage added to the material cost when calculating the estimate. |
| Stock Selling Price | A separate price field. Do not assume changing material markup automatically updates it. |
| Quotation Margin % or Markup % | A quotation-level pricing control. Its calculation depends on system settings. |
Material markup and quotation margin are separate. The material line uses a cost-based markup even when the quotation pricing grid is configured to display Margin %.
Assume you buy a 6-metre bar for £120 and record material usage in metres.
| Field | Example value |
|---|---|
| Purchase Units | Bar, using the appropriate configured unit description |
| Stock Units | Metres, using the appropriate configured unit description |
| Conversion Factor | 6 |
| Purchase Unit Cost | £120.00 per bar |
| Stock Unit Cost | £120 ÷ 6 = £20.00 per metre |
| Markup % | 25 |
A material requirement of 2 metres therefore has a base cost of £40. A 25% material markup adds £10, giving a marked-up material amount of £50 before any quotation-level pricing adjustment.
Do not change a conversion factor simply to correct a price. RedAnt warns that changing an existing factor affects purchase orders and goods-in records and cannot be undone. Review a genuine unit change with the person responsible for stock and purchasing.
Supplier quantity prices are maintained separately from the standard purchase cost on the stock record. When checking a quotation, confirm that the correct supplier price and quantity break have been used and that delivery charges are included. Check each material line after changing supplier prices.
The Default Settings screen contains a Margin / Markup % field associated with the default material markup. Agree the intended value with the person responsible for pricing before changing this shared setting.
When selecting a stock item on a quotation material line, RedAnt copies the stock item's cost, stock units, supplier and markup. Editing the material description can replace a zero markup with the system default.
If a material must have zero markup, check the final saved line after selecting the stock item and editing its description. A stock markup of zero does not guarantee the quotation line will remain at zero.
For a simple material line, the base amount is Quantity ÷ Qty Per Unit × Price; the material markup is added to that amount. Supplier volume pricing, minimum charges, assemblies and quantity allocation can change the calculation, so verify each quoted quantity.
When adding a new material line, select the Stock ID before entering a description so RedAnt can fill in the stock details. For an existing line, check the price, units, supplier and markup yourself after a price change.
Markup measures profit against cost. Margin measures profit against the selling price.
| Cost | Pricing method | Selling price | Profit | Achieved margin |
|---|---|---|---|---|
| £100 | 20% markup | £120.00 | £20.00 | 16.67% |
| £100 | 25% markup | £125.00 | £25.00 | 20.00% |
| £100 | 20% margin | £125.00 | £25.00 | 20.00% |
| £100 | 30% margin | £142.86 | £42.86 | 30.00% |
These examples exclude VAT and assume the stated cost is the complete cost basis for the calculation. A material-only margin does not establish the profit margin for the whole job.
Check whether the quotation pricing grid displays Margin % or Markup %. The Margin option in Default Settings controls this mode.
Confirm the markup basis with your administrator before setting a company-wide pricing rule. A markup applied to Estimated can build on amounts that already contain material markups.
For example, if the complete Total Cost is £100 and the target margin is 20%, the required quoted price is £125. A material markup should be treated as part of the pricing setup, not as proof that the final quote achieves the target.
When an existing stock purchase cost changes, users with Stock maintenance access may receive a prompt to change the cost price for ALL Material Plans using that Stock ID. Accepting it updates matching material-plan prices using the new cost divided by the conversion factor.
Only accept the bulk update when all matching material plans should be repriced. For a quotation-specific supplier offer, review the individual estimate rather than assuming every plan should use the temporary price.
After changing a price, check the stock cost, supplier prices, affected material plans and any quotations you intend to reuse. Update the stock selling price separately where required. Always review existing quotations before sending them to a customer.
The Stock screen also has Maintenance → Selling Price Increase and Register Plan Price Increase. Their names describe different operations; choose the function that matches the records you intend to change.
| Symptom | Check |
|---|---|
| Material cost is several times too high or low. | Purchase units, stock units, conversion factor and the line's Qty Per Unit. |
| 20% gives less profit than expected. | Whether you entered markup while intending a margin. A 20% margin requires 25% markup on the same cost basis. |
| A zero material markup reappears as a percentage. | The system default can be applied when the quotation material description is edited. |
| An existing quote still shows the old cost. | Its saved line values and the pricing source actually used for the estimate. |
| The final quoted price seems too high. | Material-line markups, quotation-level percentage and whether markup is based on Estimated. |
| Supplier discounts do not appear at every quantity. | The supplier, quantity breaks, units and delivery allocation. |
| A cost edit changes many plans. | Whether the prompt to update all matching material plans was accepted. |
