Choose a first seeding batch no larger than the smallest of four limits: packing capacity, support capacity, usable kit stock after a replacement reserve, and confirmed recipients. Calculate each limit for a named dispatch window. If you have no prior shipment data, reduce the batch until a higher-support-work scenario also fits. The hypothetical worksheet below permits 36 kits under its base assumptions, but selects 22 for the first release.
Measure the work your kit requires
A product seeding batch size starts with the finished kit. A single item with one insert takes a different set of steps from a kit with chosen sizes, several products and a personal note.
Modash's gifting advice describes three product-choice approaches: the whole catalog, one product, or a curated selection. For capacity planning, settle that choice before measuring packing time. Otherwise, you may time the shortest kit and promise a batch full of longer ones.
Run a rehearsal using the actual kit and packing materials. Include picking, checking the selected variant, assembling the package, printing and checking the label, and recording the shipment. Measure several repeats and keep the slow cases visible. A rehearsal is an estimate, so leave time for interruptions.
The Lean Enterprise Institute's cycle-time reference grounds cycle time in direct measurement. Its operator definition includes all work elements at a station. Apply that idea to the whole packing task rather than timing only the moment someone seals a box.
Keep fixed setup work separate. Preparing inserts or setting up the packing station may happen once per batch. Picking and checking happen for each kit.
Packing limit = round down((minutes assigned to seeding − setup minutes − held-back packing minutes) ÷ measured minutes per kit).
Count only time the warehouse manager has assigned after regular orders and breaks. Do not count the same person's minutes again under support. If workers share one label printer or checking station, verify that station can process the batch within the window. Adding worker hours does not remove a shared-station limit.
Fill in the batch-capacity worksheet
This hypothetical example uses one identical kit per recipient. Each kit contains one unit of the same product. The warehouse has one dispatch session, with support time reserved for the following week. Every number is a planning assumption, not a benchmark or a recommended industry rate.
| Input | Hypothetical value | What it means |
|---|---|---|
| Assigned packing time | 510 minutes | Seeding-only time after other work |
| Fixed setup | 30 minutes | Work done once for the batch |
| Held-back packing time | 60 minutes | Available for rework or replacements |
| Measured kit work | 7 minutes | Complete per-kit task |
| Support budget | 180 minutes | Separate time after existing cases |
| Routine support work | 2 minutes per kit | Shipment record and status handling |
| Extra-case allowance | 20% of kits | Base planning assumption |
| Work per extra case | 15 minutes | Average total handling assumption |
| Eligible kit stock | 52 kits | Already excludes other commitments and holds |
| Replacement reserve | 8 kits | Excluded from the first release |
| Confirmed recipients | 40 | Accepted gift and completed shipment details |
The packing limit is (510 − 30 − 60) ÷ 7 = 60 kits.
For support, combine routine work with an allowance for extra cases. Those cases might involve a recipient question, shipment investigation or replacement coordination. Count total handling time across the conversation, rather than the first reply alone.
Expected support minutes per kit = routine minutes + (extra-case share × minutes per case).
Here that is 2 + (0.20 × 15) = 5 minutes. The support limit is 180 ÷ 5 = 36 kits. This estimates workload; it does not predict which recipients will need help or guarantee the total.
| Limit | Calculation | Maximum release |
|---|---|---|
| Packing | (510 − 30 − 60) ÷ 7 | 60 kits |
| Support | 180 ÷ 5 | 36 kits |
| Stock after reserve | 52 − 8 | 44 kits |
| Confirmed recipients | Ready shipment records | 40 kits |
| Base batch ceiling | Smallest limit | 36 kits |
Packing more boxes would not raise this ceiling. Support is the limiting resource in this example.
Stress-test the support assumption
A first batch has no established extra-case rate. Test a heavier workload before using the base ceiling as a release target.
In a second hypothetical scenario, 40% of kits need 15 minutes of extra handling. Expected support work becomes 2 + (0.40 × 15) = 8 minutes per kit. The same 180-minute budget permits 22 kits after rounding down.
The team therefore releases 22 kits and keeps the other 18 confirmed recipients for a later window. It tells those recipients their revised dispatch timing before treating the later batch as agreed.
At 22 kits, the stress-case estimate uses 176 support minutes. Packing uses 154 minutes plus setup, leaving the held-back packing allowance intact. If support requests may arrive together, check who can answer them on those days. A weekly total alone does not establish daily coverage.
The 40% assumption is a chosen stress case. Replace it with your own observed workload when evidence becomes available. If even that scenario seems optimistic for your kit, choose a smaller release.
Protect the reserve in stock and time
The eight reserve kits remain outside the release count. They need matching packing materials and time to prepare them. In this example, 60 held-back packing minutes cover eight seven-minute replacements, with four minutes left. That alignment is deliberate; eight spare products without packing time would leave the plan incomplete.
Use physically eligible stock for the calculation. Shopify's inventory-state guidance distinguishes on-hand stock from stock available to sell. On-hand totals include commitments and unavailable units, including safety stock or quality-control holds. A warehouse total alone is therefore insufficient for this worksheet.
For kits with different sizes or several products, calculate the stock limit for each required variant. Eight spare units of the wrong size cannot replace eight promised kits. The separate guide to reserving inventory for creator seeding covers allocation records; use this worksheet to decide how many recipients those records can support.
Confirm the spend limit separately with the full seeding batch cost worksheet. Available labor and stock do not establish budget approval.
Release the next batch after reviewing the first
Before adding recipients, record actual packing minutes, extra cases, support minutes and reserve kits used. Keep open cases in the next window's workload. A packed box leaving the building does not end its support demand.
If the first release exposes repeated errors, use a seeding pause plan before increasing volume. Set the next batch using remaining capacity and replenished reserves, rather than the original allocation.
Ask the warehouse and support owners to fill in the worksheet for one dispatch window. Agree on the smaller stress-tested count before releasing the packing list.
