For a small office that sends a steady batch of ordinary letters, stamps are usually the simplest starting point; a postage meter or PC Postage becomes worth evaluating when applying stamps, handling variable weights, or tracking costs is taking meaningful staff time. The number of envelopes alone is not a USPS rule or a guaranteed savings threshold. Compare your actual labor, equipment or software costs, mailpiece mix, and approval process before switching.

Start with the work your team actually does
Take one normal week and separate standard letters from heavier, rigid, international, or otherwise unusual pieces. Count the time spent selecting postage, applying it, correcting mistakes, and recording what was used. If one person handles a predictable stack of standard letters, a coil, booklet, or sheet may be easier to manage than adding another device and account. If several people send mixed mail and need an itemized cost record, a printing workflow may deserve a closer look.
| Illustrative weekly workload | Practical first test | What could change the decision |
|---|---|---|
| About 30 standard letters | Time one stamp-and-log session before considering equipment. | Frequent nonstandard pieces or strict cost allocation may matter more than volume. |
| About 100 letters | Compare a consistent coil workflow with a trial of metered or PC Postage processing. | Check fixed fees, supplies, setup time, and how often postage amounts vary. |
| About 300 letters | Measure the full batch: preparation, application or printing, exception handling, and reconciliation. | Commercial-mail eligibility is a separate USPS question; 300 pieces do not automatically qualify for commercial First-Class Mail prices. |
These are planning examples, not universal cutoffs. An office mailing 30 unusually shaped pieces can have more postage decisions than one sending 300 identical standard letters.
What a meter changes—and what it does not
USPS describes postage meters and PC Postage as systems that print evidence of postage directly on a mailpiece or on a label. They can help an office pay and track postage, but some devices still require hand-feeding each piece. A meter does not remove the need to check the mail class, dimensions, weight, address, and correct amount. USPS also distinguishes ordinary stamped single-piece mail from commercial mail, which has its own preparation and permit requirements. Do not assume that changing how postage is applied automatically earns a commercial rate. See the current USPS meter explanation and USPS commercial-mail requirements.
Use a total-workflow comparison, not a per-stamp slogan
For each option, write down the weekly staff minutes, equipment or software fees, consumables, error corrections, and recordkeeping. Compare like with like: the same mailpieces, the same period, and the same level of tracking. Then ask who owns the process when the usual mailroom coordinator is absent.
- Choose stamps first when the pieces are similar, the batch is manageable by hand, and the team can maintain a simple issue-and-use record. For a recurring run, a coil may reduce package changes; a booklet can be more convenient for occasional use in several locations.
- Test a meter or PC Postage when variable amounts, repeated manual application, or cost-center reporting are the real bottleneck. Compare the trial’s full cost and time with the stamp workflow before making a commitment.
- Escalate the mailing method when you are planning a commercial mailing. Review USPS eligibility and preparation separately instead of assuming that stamps, a meter, or a particular weekly count decides it.
Where PostageGrid fits
PostageGrid sells physical stamp formats; it does not sell or operate a postage meter in this guide. If the stamp route still fits your office, use the current shop to check live formats and availability, or start a larger requirement through the volume-quote request. If the meter route wins the comparison, that is a useful decision too. Keep the mailpiece readiness check in either workflow; the payment method does not fix an unmeasured or unsuitable letter.
Editorial note: The 30/100/300-piece examples and workflow recommendations are PostageGrid decision guidance, not USPS thresholds. Confirm current postal rules and actual vendor terms before purchasing or mailing.
