The cost of a hypochlorous acid (HOCl) manufacturing project depends on the product, order quantity, fill size, packaging and work included. To compare proposals, put them on the same basis: the same finished product, the same quantity and the same delivery boundary. Then add separately quoted work and costs you will pay directly. An unresolved item should remain an open cost, not become a zero in your spreadsheet.
This is a guide to comparing manufacturing proposals you have received. If you still need to describe your project to suppliers, start with our HOCl quote-request brief.
What does the quoted unit price actually buy?
Before comparing the amounts, write a one-sentence description of the item each price covers. “One bottle” could mean a filled, labeled bottle ready for case packing, or a finished item with the sprayer, protective cap and outer packaging included. Use the proposal’s stated scope; ask about anything it leaves unstated.
Record the quoted order quantity and fill volume next to that description. A larger fill size, a different bottle or a different number of units changes the comparison. If one proposal uses a different formulation or requires development, that is a product or work difference to resolve before calling either offer cheaper.
Our manufacturing-program comparison explains how an existing formulation, custom development and a supplied formulation lead to different scopes. For the cost comparison, use the work actually quoted rather than relying on the program name.
Give the comparison a boundary too. Are you comparing goods ready for pickup, or goods delivered to the same destination with the required freight services? Either can be useful, but mixing the two makes the totals misleading.
Which costs sit outside the manufacturing line?
Read each proposal once for included work and again for responsibilities assigned to you. A buyer-supplied sprayer may be absent from the manufacturer’s invoice while still being part of your cost to produce the product.
Use four labels for every relevant item: included, separately quoted, buyer-supplied or unresolved. These labels are a review method, not a claim that every supplier uses these charges.
| Scope item | What to establish |
|---|---|
| Product work | Whether formulation development or agreed custom sample work is included, separate or outside this proposal. |
| Components | Who pays for the bottle, closure, sprayer, label and any agreed outer packaging. |
| Production work | What filling, assembly, labeling and packing the amount covers. |
| Testing and documents | Which agreed activities and records are included, and whether any requested work needs a separate quote. |
| Freight and receiving | Where the quoted price stops and who obtains the remaining transport or receiving-service costs. |
| Remaining components | What happens to any components purchased for the project but not used in this order, if applicable. |
Avoid counting an included item a second time. Equally, do not hide a missing price inside a general contingency and then describe the comparison as complete. Keep the unresolved item visible until someone answers it.
Worked example: why two unit prices are not yet comparable
Consider a fictional beauty brand comparing two proposals for the same intended HOCl mist. These are invented scope descriptions, not HOCl Connect offers or market-price examples. No dollar amounts are needed to identify the problem.
Proposal A covers filled bottles with sprayers and labels. Its scope stops before shipping cartons and freight. Proposal B covers filled and labeled bottles, shipping cartons and freight to the stated destination, but requires the brand to supply the sprayers.
| Missing comparison item | Required follow-up |
|---|---|
| A: shipping cartons | Obtain the carton and packing scope with its price, or confirm the buyer’s separate arrangement. |
| A: freight | Obtain a quote to the same destination and service requirements used for B. |
| B: sprayers | Add the brand’s confirmed component purchase and any agreed delivery cost for getting them to production. |
| Both: final configuration | Confirm the same bottle, fill volume, sprayer, label, quantity and packing requirements. |
At this stage, the lower stated unit price identifies only the lower price for the scope described on that proposal. It does not identify the lower cost for the finished, delivered order.
The brand can request revised proposals on one basis or keep the original proposals and add clearly identified, separately confirmed amounts. If a supplier cannot provide part of the required scope, the buyer needs a separate arrangement and its cost before completing the comparison.
This also reveals a practical difference: one offer requires the brand to procure a component. Record that responsibility alongside the total. A similar total does not remove the work the brand has agreed to handle. Use our guide to assessing manufacturers’ replies and supporting evidence to review what the supplier’s answers establish.
Keep first-order and repeat-order costs separate
Make two views if you are considering repeat supply: the opening project and a later order of the same agreed product. Ask which quoted items apply once, which repeat, and which depend on the configuration remaining unchanged. Do not assume development, setup, testing or artwork work is either always charged or always waived.
A repeat-order estimate should identify its own assumptions. A new fill size, revised assembly, changed formula or different quantity may need a new quote. Preserve the original price basis rather than applying an old unit price to a different product.
For each view, total only the confirmed costs within your chosen boundary. If you divide that total by units, use the same agreed finished-unit quantity for both offers and label what the result includes. Keep unknown amounts listed separately. Do not turn an annual forecast into a committed order quantity merely to make a unit-price comparison look attractive.
Build a comparison you can update
Copy the following fields into your purchasing notes or spreadsheet. Make one column per proposal and retain the original quote as the source.
- Proposal identity: supplier, date, version and any stated validity period.
- Common basis: product/formula version, assembly, fill volume, quantity and delivery boundary.
- Quoted amount: amount, currency, unit basis and exactly what it covers.
- Other scope: each separately quoted, buyer-supplied or unresolved item; its source and current amount, if confirmed.
- First versus repeat order: work included in each view and assumptions that must remain true.
- Change requiring review: a revised quantity, component, specification, destination or service requirement.
- Next action: the missing answer, who will obtain it and whether it prevents a fair total comparison.
The result should let another person reconstruct the total without guessing which costs you included. If a proposal changes, update its version and the affected lines; do not silently combine the price from one version with the scope from another.
Bring the unresolved cost question back to the supplier
A useful follow-up is specific: “Does this price include the sprayer and shipping carton for the assembly listed in this quote, and what remains for us to purchase?” That is easier to resolve than asking whether the price includes “everything.”
For a project with HOCl Connect, send us the product and scope you want priced. Identify components you plan to supply and work you want included. Your broader brand, selling and fulfillment budget still needs its own review; this comparison establishes what the manufacturing proposals cover.
