Predictika · Centralized mailbox quotes
An AI sales agent prepares a quote for a property's centralized mailboxes: which modules, how many, whether the mail is delivered by the USPS or privately, how the modules are mounted and where, the accessibility rule that applies and the door labels. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published catalog and USPS STD-4C rules and returns a verdict, every reason and the figures it computed.
This validator models a quote for the USPS STD-4C compliant versatile 4C mailbox modules in the Florence 4C Mailbox Products & Accessories catalog (43 module numbers from four height suites), not just the scenarios shown below.
Any quote for these modules that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Florence publishes no list prices, so this page shows no price build-up or line-item quote), the other height suites and the cluster box unit, horizontal and vertical lines, collection hoppers and bins, installation heights beyond what is stated for each module, colors and accessories. Assumptions: the model counts a mailbox as within Fair Housing reach if it is within 48 inches or the module is marked as meeting the 54-inch limit; combining modules from different suites is sent to a person because the catalog does not describe it.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| Parcel locker ratio from module contents | Only with care The count of lockers of at least 15 inches has to be kept for every module, because smaller lockers do not count, and compared with the mailboxes on the whole order. | The qualifying lockers and tenant mailboxes of every module are totalled and compared on every call. |
| Delivery type against mounting and module choice | Only with care Whether a module or a mounting method suits USPS delivery depends on notes in the catalog, so each combination needs its own rule kept in step. | Delivery, mounting, location and module are checked together on every call. |
| Accessibility rules that vary by property | Only with workarounds The 5 percent, 100 percent and Fair Housing cases count different things, and the 5 percent case needs a person to confirm with local officials. | Each rule is checked against the reach figures of the modules ordered; the 5 percent case goes to a person. |
| Totals that must match what the quote states | Only with care The mailbox total comes from the modules and quantities and has to agree with the figure written in the quote. | The total is computed from the modules and compared with the stated figure. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.
| 1 | The property needs 70 tenant mailboxes; the modules on the order give 60. |
| 2 | USPS delivery to a multifamily property needs one parcel locker of at least 15 inches for every 5 tenant mailboxes; the order has 6 such lockers for 60 mailboxes. |
| 3 | 2 modules on the order are marked in the catalog as not meeting the USPS installation specifications (private delivery only). |
| 4 | USPS delivery to a multifamily property needs one parcel locker of at least 15 inches for every 5 tenant mailboxes; the order has 9 such lockers for 60 mailboxes. |
| 5 | The catalog states that surface-mount collars and depot cabinets are not a USPS approved installation method; only recessed mounting is. |
| 6 | The catalog lists the surface-mount collar for indoor use only. |
| 7 | A depot cabinet is a freestanding single-unit solution; the order has 2 modules. |
| 8 | The catalog offers depot cabinets for the Max Height, 15 High, ADA Max Height and 6 High suites only; the order includes an 11 High module. |
| 9 | USPS STD-4C needs at least one customer compartment less than 48 inches above the floor; none of the modules on the order has one at its recommended installation height. |
| 10 | The ADA rule needs at least 5 percent of the mailboxes, and no fewer than one, within reach; the order has 0 of 5 within 48 inches. |
| 11 | USPS delivery to a multifamily property needs one parcel locker of at least 15 inches for every 5 tenant mailboxes; the order has 4 such lockers for 40 mailboxes. |
| 12 | The property needs every mailbox within ADA reach; the order has 16 of 40 within 48 inches. |
| 13 | The property has 50 covered dwellings needing Fair Housing reach; the order has 16 mailboxes within 54 inches. |
| 14 | The door ID has 6 characters; decals take up to 5 and engraving up to 12. |
| 15 | The door ID has 13 characters; decals take up to 5 and engraving up to 12. |
| 16 | The quote states 64 tenant mailboxes in total; the modules on the order give 60. |
| 17 | The two modules come from different height suites; the catalog gives dimensions and installation heights per suite, so a person should confirm the layout with an authorized dealer. |
| 18 | The quote uses the 5 percent ADA rule; the catalog notes local authorities can require 100 percent, so a person should confirm with the local building officials. |
| 19 | 1 of a second module are ordered but no second module is selected. |
| 20 | A second module is selected but its quantity is 0. |
| 21 | The order needs at least 1 of the first module; it has 0. |
