Conversion charges for food contract manufacturers that cover the real cost
A contract manufacturer earns a conversion charge per unit and carries every loss the contract does not price. We cost each brand owner's products from line time, changeover and actual wastage, and reconcile the brand owner's material to every unit produced. We also show which contracts cover their share of the plant.
In one paragraph
When a brand owner supplies the recipe, the material and the packaging, the manufacturer's income is a conversion charge. Its risk lies in wastage, capacity and material held on someone else's behalf. Food, beverage and personal-care contract manufacturers producing for one or more brand owners usually turn over ₹10–300 crore.

The economics
How the money moves in this trade
A contract manufacturer may buy materials and sell finished goods, or work on material supplied by the brand owner and charge only for conversion. Many run both models for different customers. Contracts set wastage allowances, minimum volumes and price-revision clauses, and the brand owner audits the plant and the material account. When actual wastage exceeds the allowance, the manufacturer pays for the difference.
Plant capacity is shared between brand owners with different pack formats, recipes and hygiene requirements, so changeovers and cleaning take up much of the line's time. A contract with low volume and frequent changeovers can consume capacity worth more than it pays. Material belonging to brand owners must be accounted for as job-work stock under GST and agreed with each brand owner's records.
The problem
Where the numbers usually break down
Conversion charges are not tested against line time
The per-unit charge is negotiated at the start of a contract and never compared with the line hours, labour and utilities each product actually consumes.
Wastage beyond the allowance is absorbed
Actual material and packaging loss is not compared with the contractual allowance, so excess loss is paid for without being noticed.
Brand-owner material is not reconciled
Material supplied by brand owners is tracked in a register that does not agree with the brand owner's account or the GST job-work records.
Changeover time is not charged
Cleaning and changeover between customers' products is treated as idle time rather than as a cost of the short runs that cause it.
Capacity is allocated without regard to margin
Line time goes to whichever customer asks first, with no view of which contracts earn most per line hour.
What we do
The work, and the result each part produces
Conversion costing by product
Cost per unit from line time, labour, utilities, consumables and quality checks, compared with the conversion charge.
Every product shows whether its charge covers its cost.
Wastage against contract allowance
Actual material and packaging loss by product and batch compared with the allowance in each contract.
Excess wastage is identified and either fixed or renegotiated.
Brand-owner material reconciliation
Material received, consumed, returned and lost reconciled by brand owner, and agreed with their account and the GST job-work records.
Material accounts agree with each brand owner's records.
Changeover and short-run costing
Cleaning and changeover time recorded and charged to the runs that cause it.
Short runs carry the cost they impose on the line.
Contribution per line hour
Contribution per hour of line time by contract and product.
Capacity goes to the contracts that pay for it.
Contract terms register
Wastage allowances, minimum volumes, price-revision clauses and audit rights recorded per contract, with revisions tracked.
Each contract is managed against its own terms.
Where we start
The first steps of an engagement
Contracts, material ledgers and line logs
We ask for each brand owner contract, material and packaging received and consumed by brand owner, the GST job-work records, and line logbooks showing run and changeover time.
Conversion cost against charge
For the main products, cost per unit from line time, labour, utilities and consumables is compared with the conversion charge. Actual wastage is compared with each contract's allowance.
Material account and terms register
Brand-owner material is reconciled to their account and the job-work records. Wastage allowances, minimum volumes and revision clauses go onto a contract register.
First contract contribution report
Conversion cost against charge by product, wastage against allowance, and contribution per line hour by contract.
How it is measured
The reports the work is judged on
Each is recorded as a baseline before the work starts, so later reports have an honest comparison.
- Conversion cost against conversion charge, by product
- Wastage against contractual allowance
- Brand-owner material reconciled and agreed
- Changeover hours and their cost
- Contribution per line hour, by contract
- Price revisions due against claimed
Who it suits
Written for, and not the right fit for
- You manufacture only your own brand — the packaged food page is a closer match.
- You are a pharmaceutical contract manufacturer — the pharmaceutical pages address that work.
- Food, beverage and personal-care contract manufacturers producing for brand owners.
- Manufacturers working on brand-owner-supplied material and packaging.
- Firms renegotiating contracts or deciding whether to take on a new brand owner.

Common questions
Questions owners in this trade ask
Our conversion rates are set by the brand owner. What can we change?
Often more than it seems. With product-level cost you can show which products are under-priced, ask for revisions under the contract's own clauses, or propose changes to batch sizes and changeovers that reduce your cost.
The brand owner audits our material account. How do you help?
By keeping the reconciliation current every month and agreeing it with the brand owner's records, so an audit confirms what you already know instead of uncovering differences.
Who holds the FSSAI licence for products we make?
That depends on your arrangement and is your and the brand owner's responsibility to settle. We support the production and material records behind it.
FSSAI licences and food safety compliance for products made under contract are the responsibility of the manufacturer and the brand owner. 5th Quadrant supports the production, material and job-work records; statutory and tax-audit reports are signed by an independently engaged CA. Full detail is on our Professional Scope page.
