About us
Who is Double Support?
Double Support is a technology company with 180 people across three offices. We build software, we run English-speaking call center teams for companies in the United States and Europe, and we make Zyntra OS, our own business management system. The company started in Amman in 2014 and is led by its founder and CEO, Ayman Aljakhbir. More about us.
What does Double Support do?
Three lines of business from one company: software development and support (applications, APIs, integrations, and the hosting, infrastructure, backup and security behind them); call center agents on calls, live chat and email; and Zyntra OS, with the online essentials around it — web hosting, business email and domain registration.
Where are your offices?
Our head office is in Amman, Jordan, in the Faisaliyah Center on Wasfi Al-Tal Street (Gardens), where our software team and our call center agents work. Our second development center is in Tbilisi, Georgia, and our United States office is in St. Petersburg, Florida.
Is Double Support an approved e-invoicing provider?
Yes: in Jordan's National Invoicing System (JoFotara), and with the Zakat, Tax and Customs Authority (ZATCA) in Saudi Arabia. E-invoicing in Jordan and Saudi Arabia.
How Zyntra works
What is Zyntra OS?
Zyntra OS is the business management system Double Support makes in Amman. It runs sales, projects, inventory, accounting, HR and much more in one system, behind one sign-in, so your team works from one set of records — and it is built to be easy, so a new person does not need a course first. See Zyntra OS.
Which modules does Zyntra OS have?
Dashboard and My Space; Sales and CRM; leads and deals; contracts and subscriptions; projects and tasks; expenses; accounting and e-invoicing; purchasing; inventory; logistics; fixed equipment; HR, payroll, timesheets and leave, and recruitment; support with a knowledge base; the client portal; and appointments. Every installation includes reporting and a full audit trail. You take the modules you need.
Can one Zyntra run more than one company?
Yes. Each record belongs to its company, each person works in the companies they are given, and they switch between them from the top bar. A company sees only its own records.
What is the client portal?
Your own customers sign in to their portal and see what is theirs, such as their invoices and projects; they open support tickets there, and ask Flowrica about their own invoices and projects. The portal is included with a set number of portal users.
What does Flowrica do?
Flowrica is the assistant built into Zyntra OS, in a panel beside every screen. She answers from your own records and shows where each answer came from, fills the section's own form one question at a time, reads the papers you upload, and drafts your emails and replies. Nothing is sent and no record is made unless you press it. Meet Flowrica.
How does a new Zyntra start?
Two ways. Ask for a demo — from our contact page, or by calling or emailing us — and our team gets back to you to show it working. Or build your Zyntra on the pricing page and send it: the request reaches our team, and your Zyntra is opened once we approve it. There is no self-sign-up; we set it up with you.
How does e-invoicing work in Zyntra OS?
Each company chooses in its own settings whether it uses national e-invoicing, and for which country; a company that does not, sees nothing of it. For Jordan, an invoice issued in Zyntra is submitted to the National Invoicing System (JoFotara) and comes back carrying what the system gives it, such as its QR code. For Saudi Arabia (ZATCA), talk to us about connecting your invoicing.
Frequently asked questions
How much does Zyntra OS cost?
You pay for the people who log in and work in the system, and for the modules you take. On the pricing page you pick the edition, the modules you need and how many people will use it, monthly or yearly, and the price changes as you choose. The price you see is the price on our invoice.
How much does Zyntra Legal cost?
Zyntra Legal is one of the editions on the pricing page: choose it there to see its price with the modules your office takes.
How is the call center priced?
Per agent, per month, for full-time agents. You start with two agents, for three months, then month to month. Tell us your hours, volumes and channels and we will quote you; the call center page shows where prices start.
Do call center clients pay for Zyntra OS?
Every call center client gets Zyntra OS at a preferential price, and larger teams get it free.
Can I see Zyntra OS working before I decide?
Yes. Ask for a demo on our contact page, or call or email us and say you would like one, and we will arrange it with you.
How do we start with Zyntra OS?
Build your Zyntra on the pricing page and send it, or talk to us. Your request reaches our team, and your Zyntra is opened once we approve it. There is no self-sign-up: we install it and set it up with you, for how you work.
How quickly can a call center team start?
In two weeks. For a language the team does not already staff, allow four to six weeks.
Do you connect invoices to JoFotara and ZATCA?
Yes. Double Support is an approved e-invoicing provider in Jordan's National Invoicing System (JoFotara) and with ZATCA in Saudi Arabia. See e-invoicing in Jordan and Saudi Arabia.
Do we have to change our accounting system?
No. We connect the system you already invoice from to the one your country runs: your system keeps issuing invoices, and each one is submitted as it is issued. If you are choosing a new system, Zyntra OS has e-invoicing beside its invoices and accounting.
Does Zyntra OS work in Arabic?
Yes. Every screen works in Arabic and in English, and each person chooses their own language. You can give Flowrica your answers in Arabic too.
Can your agents answer our customers in Arabic?
Yes. Our agents are in Amman and Arabic is their first language. Arabic-language teams work Sunday to Thursday by default, the Gulf week, and can be arranged around your own working week.
How do we get support?
Every Double Support client has their own portal in Zyntra OS, and a support ticket opened there reaches us faster than a general inquiry. You can also call or email us; inquiries get an answer within one business day.
When are you open?
Saturday to Thursday, 9:00 to 18:00 Amman time (GMT+3). Fridays and evenings are covered by a standby team for urgent issues. Our call center team works its own shifts, on your hours.
Where is our data kept in Zyntra OS?
Each company gets its own installation and its own database, so your data does not sit beside another company's. Every installation keeps a full audit trail of who changed what.
Does Flowrica show people what they should not see?
No. Flowrica never shows anyone a record they could not open themselves, and the company chooses which roles see her at all. Nothing is sent and no record is made unless a person presses it.
Where is European clients' call center data stored?
In the EU. Calls run through Twilio's Ireland region and Zyntra OS is hosted in Europe, and a Data Processing Agreement is signed with every European client. See our Privacy Policy.
Can you move our data from the system we use now?
Moving data from an older system into a new one is part of our systems integration work. Tell us which system you use today and we will tell you how we would move it.
Will the business stop while we switch?
Getting a system live means switching the old way off without stopping the business. We install and configure the system, connect it to your other systems, go live with you, and stay close afterwards. See implementation and deployment.
Can we keep our domain and our email?
Yes. You can transfer a domain you already own to us, or keep it where it is and we point it at your mailboxes. Existing email and contacts can be brought across with a one-click import. See domains and business email.
