The best phone system software for trades
Customers text a trade number more often than they call it. That is where these plans get stingy. RingCentral's cheapest tier includes 25 texts per user a month, and its free trial does not turn texting on at all. OpenPhone includes unlimited US and Canada texting instead. Compare the message limits first, then the call features (as of August 2026).

What decides it in phone & VoIP
Count the texts each plan gives you
One job can take six or eight messages back and forth with a customer. RingCentral Core includes 25 texts per user a month, and Advanced raises that to 100, so whoever answers your phone runs dry in a few days. Its 14-day trial has texting switched off, which means you cannot test the part you care about most. OpenPhone includes unlimited texting to US and Canadian numbers on every plan, after a one-time carrier registration fee. Podium is built around a shared texting inbox and needs 10DLC signup, which is the carrier registration every US business goes through before it can send business texts. Whatever you pick, expect a short registration step before your first text leaves the building.
Per user, and monthly billing costs more
Both phone-first tools charge per person, so the bill tracks your headcount. OpenPhone Starter is $15 per user a month on annual billing, or $19 month to month, and extra numbers are $5 per user a month. RingCentral Core is $20 per user on annual, or $30 if you pay monthly, which is half again as much (as of August 2026). For six people that is $90 a month on OpenPhone or $120 on RingCentral, before telecom taxes and fees. Then look at what your tier holds back. OpenPhone records only when you press the button until you reach Business, and a phone menu with a set ring order needs Business too. RingCentral Core records on demand only, and recording every call means Advanced or Ultra.
Neither one tells you which ad rang
If you spend money on ads or a paid listing, you want to know which one made the phone ring. Neither dedicated phone tool does that on its own. RingCentral has no ad tracking built in and plugs into CallRail, which arrives as a separate bill. OpenPhone has no ad source tracking either, though its Business plan shows call volume per number, so you can point one number at one ad and count. Workiz is the exception in this category, because its phone system sits inside the job software and tracks calls and ad sources against real jobs. If knowing where your calls come from is the reason you are shopping, that one fact should reshape your shortlist.
